oh yes, he was one of the nicest people. We saw him at a non trek event, a play he was in. We hung around afterwards in hope that he might come out and we could say a few words t him. We found out that he wasn't going to come out and we were about to leave when we overheard a group of women talking about waiting for their good friend bob picardo. well we snuck over and causally started talking to them, when he came out he offered us an autograph, even dug through his own bag for a sharpie
I don't think I have ever heard a bad fan experience with Robert Picardo. He seems really sweet and nice on his Facebook, Twitter, etc...and all of the fans I know that have met him all seem to think so as well.
