Truth is, the area was probably above carrying capacity when the numbers were so high, especially the buck numbers. There was so much competition between bucks that many mature bucks were dieing before the depth of winter even hit them. Also, when an area gets hit so hard with so many fawns and mature bucks killed, it takes many years for the numbers to rebound. 3 years is not enough. Maybe in another 3 years, with winter cooperating, there will be good numbers there again. The Gunnison area has a lot of good winter habitat, but it is higher elevation than a lot of other areas.
Having said all that, it is still a good place to hunt, just fewer animals to chase. I wouldn't spend too much on a voucher. The voucher prices pre-winter kill was $4,000+, I wouldn't give $2,000 now.
