I've searched my boring past and found no one that I can recall that I can truthfully say I've met and had a conversation or got to shake their hand, etc that I could say is famous. What a brown paper bag life I have lived!
I've seen a few up close,,been snubbed by a few in an attempt to meet & converse, but never more than that.
I've done work for, or done work on, guns that were owned by some famous folks. Some of the guns were being done up to be given as gifts to some of them. Never got to meet any of them as the work was all done third party and the front company gets the credit in that situation unless they choose to get you involved,,and they didn't.
If that counts,,I'll toss in John Milius, Prince Andrew (and he was in town too to watch the Ryder Cup at the time but didn't stop by), Leonid Brezhnev, Hank Williams Jr, Jimmy Carter (hey,,he's a quail hunter & it was almost 20yrs ago!), Tom Selleck,,. Wish I could remember more to make this sound better!
