I was in the eastern side of the Bridger area from Nov 15th-26th. I didn't see a single antelope while driving through the BLM land. I had seen 2 dozen plus in the same area the previous October 15th-25th. I'm not sure which one was normal, so take my tiny sample size for what its worth.
They could always recover, but it would take several years of favorable weather to do so. This winter is looking good for them, now we just need 3-4 more. I really wish they would just get rid of doe tags
