Steve,
I hunted out of Dease Lake BC 4 years ago. I did not hunt with Bradford and do not know anything about them. I hunted with BC Safaris. My buddy and I both killed good sized moose and I killed a nice mtn goat and he got a good caribou. We also saw lots of stone sheep.
I obviously can't comment on the outfitter, but there was plenty of game in area. I would reccomend BC Safaris, and I would assume since the outfitter you asked about operates in the same general area that they may have similar numbers of game.
What are you planning to hunt?
