Greetings from northernmost California.

Welcome! Sounds like a great lineup of trips. Be sure to share some photos afterward! I've never been to the Trinity Alps, or anywhere in California, for that matter.
will be first trip outside of CA in 40 years of hiking.
Excellent! What parts of ID, MT, and WY are you going to be visiting? I'd imagine Yellowstone is on the list since it's right where the three states meet. And then the Tetons as well.
Yay another person from CA!
Glad to have you! Looking forward to your trip reports so I can find new places to go. :)
Trinity Alps is currently my favorite in California, so far.
