RE: Looking for info on Units 10 & 12 in Idaho.
Sanman,
I have hunted unit 12 and unit 17 (just south). I believe 10 would be very similar country. It' s steep mouantains with thick forests. The first thing I would say is tough hunting. The game seems to be scattered and since it is totally forested hard to glass. However, no doubt there are elk in there and there are some monsters. The thick forest protects them and they grow old. It' s almost all public land and you will not have to worry about getting permission of paying tresspass fees. It will not be crowded at all. Another positive is as you know tags are over the counter. Have fun.
