I really like that part of the PNW. My wife and I hunted the headwaters of the Yaak for almost a decade, with pretty good success. One 10 day trip we took a mulie each, a whitetail each, and a nice 6x6 elk. On another outing there, we watched a big cougar chase a couple of bleating whitetails down a creekbed, and our friends in a nearby camp had a grizzly charge into the camp as they were lighting the evening fire; George dropped it in the firepit, right next to where Dave had been standing seconds before!
Rivers here are very high too, we're on flood watch on the Fraser right now, which has normally crested at the end of May.
