Every year starting May 1st in Wyoming you can hunt antlers. The elk and moose and deer are usually sheds.
Hundreds if not 100's of people head into the mountains to collect them. At 18.00 a pound you can do really well. The boy scouts get the first crack at the feed grounds and depending on how much snow that year they can do very well funding their troops.
My hubby is a hoarder of shed and there is a stack as tall as the ceiling in my barn loft.
