I have tried quite a bit. We've had a chance to shoot one in WMU 300 (was just small, it was late in the day and far from truck so we passed, only a 5' or so) but permission can be hard in the spring (farmers busy, don't want guys everywhere) and grizzlies seem more plentiful than blacks. Nice time of year to be out however.
Edit, thought i'd add the bear huntings usually best come fall in the area. My buddies remove a few each season, nothing huge yet (6.5' biggest) but lots of color morphs. Castle and area on the berry patches. The have seen up to 10 a day on the one mountain towards the ski hill. Up to 7 grizzlies in a day also, that more than theres supposed to be if i remember correctly :lol
