I go every year, solo. I kill 3-4 antelope a year as we love antelope meat. I always kill a 70"+ buck yearly, but I set aside 8-10 days to hunt. This year, I had 5 days to scout and 9 days to hunt. I put 1300 miles on my truck on gravel and LOTS of miles on foot. I saw ONE buck on public... at 800 yards and running onto private. I only saw a few does on public. We have been going out there for 24 years as my wife grew up there and I am retiring there in a few months. Building a house outside Buffalo right now. I bet I saw less than 5% of the antelope numbers I usually see. Found dead ones. Talked to other hunters who had covered about 21 miles on foot in three days and they saw not one live antelope on public, but also found dead antelope. They were hunting the GMU next to where I hunted. The drought was the worst I have seen in 24 years out there. The rancher I stay with said it was the driest he had seen it since he moved there 30 years ago. He had to pay another ranch (in a drainage/valley) that had some grass... to let him graze his cattle on.
I talked to some guys staying near where I was and they said they called WY Game and Fish and were told the antelope were stressing and dying. They packed up and left early. I quit hunting three days early. I did kill a decent muley, but never dreamed I could do my annual trip and never kill an antelope.
