I got to ride on one of those restocking runs once a million years ago when I worked for the DWR. Had no valid reason to be there, I mostly just ran the dumb end of the rod doing survey work in the engineering dept. (which took me to almost every fish hatchery in the state), but my boss arranged it for me just because he knew I'd love it.
Got paid minimum wage, which at the time I think was $2.35 an hour. Steady 32 hours a week. Best summer job ever.
