Long story, but it was the most epic "adventure" I've had in the outdoors.
"Scary" was short-lived, fortunately, but I will admit for at least an hour I was pretty freaked out...
Red River Gorge, Kentucky, 2001. I was way off trail exploring rock shelters and cliff lines, looking for arches with my girlfriend and another friend. It was summer, early evening and humid with sunlight filtering through the tress...stunning, I recall. I saw a nice wall that looked like it might hold some surprises...on my way up, hiking through a beautiful bed of ferns I feel a sharp pain in my ankle, probably a big thorn I thought. No biggie, off-trail hiking out there always leaves scars...I reach down to pull it out and there's a small copperhead coiled up, not at all happy that I almost stepped on it. Apparently he showed his displeasure by biting me...5 times. What's crazy is that I felt 1 bite, a bee sting is much worse (initially!). Needless to say I screamed rather loudly, pointed to the source of my odd behavior and started to think the worse. What if I'm allergic? How the hell are we getting out of here with nothing but rough terrain, no trails and 20-100' cliff everywhere? As the crow flies we were only 2 miles from a road, but its very slow hiking up and over deadfalls, route finding around cliffs and streams.
My girlfriend at the time was a volunteer at a girl scout camp and was prepared. She sat me down immediately, broke out her Sawyier Extractor Kit and told me not to look. Within a few minutes of the bite she used those suction cups...the pain was much worse than the bite, but in the end it ended up getting enough of the venom out to save me from any tissue damage. I don't even have a scar today from it.
What I did have, just minutes after being bitten, was a left leg swelling alarmingly fast...it was to my knee within an hour. After about 15 minutes of pure terror, I calmed down and we tried to figure out the next step. I had no other effects, not even an elevated heart rate, just swelling so I figured I'd live but it was going to be a loooong night.
My friend was also prepared. He liked to hike with a full backpack just for exercise, and he had a sleeping bag with him that time. Of course it started to rain lightly, but we got a small fire going and I bundled up and chilled out. His phone had just enough juice to dial 911 and he got in touch with the local county sheriffs office. Phones don't work out there, how it did that night I will never know. After trying to explain our location to no avail, she contacted the Forest Service. We were in luck...a ranger was doing trail work a few valleys away and was notified on his radio. We communicated by yelling once he got close enough, and finally he got to us at 8pm...2 hours after the bite. He took one look and called in the rescue team. They couldn't helicopter in because of the dense fog that developed, so they had to get a team to hike in. The first question they asked him..."Is he from Ohio?"...Ohioans are very well known to be responsible for at least 80% of the rescues down there. I said no, I'm local enough and they said they would make it out that much faster

The team got to me around midnite, 6 hours after the bite. At that point the 4 of us are just joking around, normal conversation...me with my balloon leg, not much pain but just intense pressure. My leg finally stopped swelling just above the knee, apparently the biggest danger was how far that swelling would go. And it sucked, but I was very fit (they said that was also a big factor, the healthier you are the the better your chances of having less trauma), had everything I needed and knew I had a great story to tell one day.
8 of them arrived with a stretcher and gear. They asked me if I could rappel, it would save them at least an hour if not more. We spent years rappelling in the Gorge so it was 2nd nature...but never with one leg, off a 70' cliff. It went smooth, they got me in the stretcher and took turns, 4 at a time, hauling me out of some of the roughest terrain in the state. it took them another 5 hours to get me out to the road...2 miles...to an awaiting ambulance. When I got to the hospital, a small town affair well versed in snake bites, they pulled out a glossy card (looked like a Waffle House menu) with a bunch of snakes on it, asking me to identify which one it was. I thought that was pretty funny...if it was a rattlesnake I'd be much worse off, and that is the only other poisonous snake in the region. I pointed to the cobra just for laughs.
2 weeks on crutches with people waiting on me hand and foot, friends stopping by for the story...my 15 minutes of fame!
I couldn't thank those good ole boys from Menifee County S&R enough, they were awesome. They kept asking me how I was doing on the stretcher, and I was more worried about them becoming another victim on that brutal hike out. We talked and joked...apparently I interrupted a pizza and beer affair. A week later I sent them a check for $50, writing "Pizza and Beer party" on the memo. I became friends with the Forest Service guy, and even helped out with some GPS trail work for them.
To this day I have no markings from the bites, and that little guy loaded me up with venom. Sawyier kits are not recommended, but I think because of the fast action...within minutes of the bites...that it saved me from tissue damage.
Side story - They wouldn't let my friends and the Forest Service guy rappel during the rescue, they had to find another way due to liability issues. During that scramble they found an unnamed arch. When the USFS was updating their arch GIS database, I was asked to name it...its called Copperhead Arch.
I now have a tattoo with the Chinese zodiak of the snake on my left ankle.
