A friend of mine tried to do something similar at that same auction.......
Was out berry picking with his wife, had to DLP a unit of a grizz, and reported it to the Troopers. Largest bear in that area in a long time, and the season opened up the next day. Trooper himself said "damn, I would have probably just kept my mouth shut on such a bear, amazing bear, sorry."
Bear had some distinguishing features that he knew which one it was at the auction. Said price went WAY higher than he wanted to spend....... and he kicks himself all the time for not spending it, now.
