btw even yellow/white units according to eastmans' system can be legally accessed and hunted even though it's very limited.
but do your research and find a unit ideally with some chunks of public blocked together vs. all checkerboard.
also part of the hunt is getting out there and having a look around, so don't stress if on the drive out to WY you aren't exactly sure where you'll be hunting etc..., have some spots circled, if one doesn't have access, check out your other spots.
