I hunted Shirly Basin (47) in '05. Saw decent numbers, but nothing big like 7 Mag said. There were some good bucks on private land, however. I drew a type 2 leftover tag, so number of hunters wasn't too bad, but I'd guess opening day would be a bit crazy. I agree that I wouldn't spend 2PP on a tag. I would think you'd have a good shot on a 2nd choice. Cna't help you on 90.
