General mule deer units with public land in Idaho are tough to find good deer these days. Scouting is key. I know that's not a great option for an out of stater, but it will help more so than normal in this instance.

Anything with roads or is relatively easy to hike will be STUPID crowded in the general season/public areas. Pray for nasty weather to keep crowds at bay.

There are still some great deer available though, if one works for them.
