While working for the USFS (1980’s) I helped trap (with nets and a helicopter, a story in it’s own right), tag with radio collar, and release, dozens of Elk that migrated from Yellowstone into Idaho winter range. Mostly the species Homo sapiens needs to leave wildlife alone.
At the time I lived “on” the Henry’s Fork (two blocks away). I lost interest in catch and release when my son and I would catch many of the same fish multiple times, mostly for our own amusement, as we pretended to to be environmentalists.
