Just call the Clearwater regional office, tell them what you're up to and ask if there's ANYONE that can help. I'm not supprised they didn't give you the CO's #. The CO for that region has whole hell of a lot of country to patrol, and is plenty busy. Some of the biologists in the office might help.
My experiance is that F&G people aren't always too helpful because most don't get into the field as much as they want to. Look up IOGA (idaho outdoor guides association) and call a few outfitters.
Bottom line is if you're gonna DIY, you just gotta go up there and try. Pick a spot that has a lot of variety in habitiat (clearcuts, heavy timber, brush, swaps ect), a wide range of elevations, and not too many roads. Once you pick a spot you're just going to have to see whats going on there for yourself.
I can tell you, and other people from the area will back me up on this I'm sure, that its not so much a matter of finding a god spot on the map, but a good spot in the woods.
Good Luck
