We hunted elk up the Greybull River several years ago. Mulled applying for deer at the same time, but the biologist I spoke with said very few deer in the area and finding a big buck would be a challenge. He didn't lie. We never did see a deer the whole time we were in the wilderness. Go check out Sundeens website who is about the only outfitter who hunts the area. I don't think I've ever seen a deer pic on his site.
