Antelope are curious. Guys have lured them in with a pair of old long johns on a stick, flying as a flag. Aluminum pie plates too. Just stuff hung out in the wind, to get their attention.
A couple years back, there was a bit of an outcry, as the Fish an Game folks in Sask., managed to overlap the seasons for Bow and Rifle hunting. Problem was, the common practice for the bow hunters, was to use a 2D decoy to hide behind, and shoot when a antelope came in close enough. Not a good place to be when the TV Star wannabe, with his long range rifle and scope, is taking shots from 600 or more yards out....
While I was first living in Moose Jaw, there were a lot of opportunities to hunt Antelope there, One bad winter, and they pretty much all moved to Montana, though, and it was shut down for a few years. Wish I had had a digital camera, as I was out delivering some Honey to a customer on their property, and drove by a Antelope standing in a field. I stopped and walked up, and there was a new born speedgoat, scrunched up and trying to be invisible in the stubble. Cute little bug, and a great thing to see after they had all but vanished from the area!
