This^^I’m an Idaho resident. My opinions.
Deer - probably slight edge to WY
Elk - WY all day, look no further than gen tag
PH - WY by a mile
Trophy species - I could go either way
Turkey - Idaho
Wolf/lion - even
Fishing - Idaho (I’m a lake guy)
Waterfowl - probably Idaho
Predators - even
Overall big game - WY
Overall other stuff - ID
I’d guess it’s a lot cheaper to buy in a nice area of ID vs same of WY. WY is a rough winter, hence the population.
Would have loved 5-6 yrs of hunting Reg G Deer and elk almost anywhere, but I love Idaho, despite all the transplants coming in.
