Don't shoot the 1st one you see. Lots of antelope in WY. If you blow a stalk don't worry-----more goats around the next bend.
Horns--------use the ear as a guide. Prongs should be above the ear & horn should be at least twice as long the ear.
Get the hide off as quick as you can. You need to cool the meat as quick as you can. If you want to mount the head----get it frozen, caped or to the taxidermist as quick as possible. The hair will really slip on an antelope.
Antelope hunting is just plain FUN-----Have a ball----Good luck. CB
