Speaking of bear suits in hunting season, one year a friend of mine put a mounted deer hear, 4 point black tail, in the brush, with the antlers visable, on a dirt road frequented by hunters and we counted 20 bullet holes in it at the end of the first day. Going about in a bear suit is not a good idea!
oops, deer hear=deer head! Sorry.
Some Wildlife agencies set up mechanical deer as you and your friend did and they do nab a few unscrupulous "road hunters".
Watching some video of the sting can be hilarious when the shooter knows he nailed the "deer" and it doesn't even flinch.
