Just down the road from me is a defunct museum called the Idaho Heritage Museum. A pot collector near here had a huge collection of artifacts he'd been collecting since he was a boy. He raised the money to open his own private museum to show it off. He also had an amazing collection of big game mounts that he'd shot over the years. You'd have to see his mule deer collection to believe it.
He had barely opened the doors when the feds moved in saying he'd collected most of his stuff illegally. Before the trial was over, he admitted that he'd got most of it along the Snake River in so. Idaho, all on public land. They confiscated all of his stuff and the place has never reopened.
Since then there have been rumors, unsubstantiated as far as I know, that many of his fabulous mule deer were taken 'under the radar' as those in high places might call it.
