Hunter2012---You are definitely correct in that assessment. I hunt a ways nw of Casper up in the BigHorns and a pack came in up there two years ago and killed over 100sheep and calves on the ranches next to where I hunt. The Father of the Federal guy that was assigned to the case told me his son ended up getting 3 of the 8 they think was in the pack and he had to do that by air because trapping didn't get any. The alpha male he shot had a collar that was put on up north of Gardner, MT!!! The Feds are keeping that incident very quiet and it never even made the local papers, but I know some are still in our area because we found a big track in the mud last September while helping the neighboring rancher where the sheep were killed fix his fence.
