Just to follow up on a couple of the folks mentioned here. I've had the pleasure of chatting with Herb Jefferson Jr. many times. He is absolute class, as far as I'm concerned. Friendly and approachable. Always says hello when he sees me, and asks about how my son is doing. A true gentleman.
I'm a little surprised about Bruce Boxlietner. I met him years ago. He was chatty and friendly. He talked about his involvement on the board of governors for the space station. He had talked about the desire to try and get another teacher in space. He laughed at my joke about how I'm a teacher, and I could name a lot of children who would love to see me in space. It's a shame that's not his normal attitude at conventions. But as others have said, you never know what's going on in someone's life.
I've never met TIm RUss, but until reading the post today, I've never heard negative about him. Goes to show, I guess.
