I always thought lakers were introduced by some private bucket biologist. Not so?
That is the general thought, but some people who were around Yellowstone and in the know when the lakers first showed up have pretty good info indicating the NPS may have had more to do with it than anyone is admitting...no way to prove anything though so don't take this as gospel...
