This sounds like a pretty good sized Wolf track, sure isn't any Coyote.

Get used to it.
They are all over Idaho and looking for new territory to expand into.
There will be appx 500+ wolves in Idaho this year.
Something better happen soon or hunting is going to continue to go into a downward spiral.
IMO they can be in the wilderness areas and national parks but the minute they step out they should not be protected.

recommend a 300 RUM, 200 grain partition with 85-90 grains of IMR7828 - works well with bears also - KMule

Yep! Guys, I have to agree with both of you!
