We also have a quite long (distance) Antelope migration, from around Jackson to the Pinedale area. There is also a mule deer wintering area in SW Wyoming (Nugget Canyon) which used to have an average annual number of deer killed on Hwy. 30 at 600 plus. Wyoming G&F spent a great deal of money, constructing fences and tunnels beneath the roadway to reduce the number of highway kills! memtb
