Pick an area that has a river or a big canyon in it, lower elevation, and hunt the south facing slopes in the afternoon as they will green up first. After a few weeks in April, evey thing is green and then just hunt the openings or "breaks" counrty.
If you wait till the snow is out of the high county (may-june) more country will be open, but the bears will be spread out a bit more.
Salmon River, Snake River, Clearwater River, and many others or large tributaty creeks fit that description. The harder it is to get into the area the better chance at a BIG bear and less chance of a hound hunter stirring things up for you.
With the late winter we are having in Central Id this year, I suspect that the low elevation bear hunting will be fantastic, as many high country bears will come out of the den to sevearl feet of snow and move down into those areas.
good luck.
you should also bring your shot gun or at least get a Turkey tag as you will likely run into several Toms as well.
