I fell in love with "Adam", when I was a very young girl. He was way cool. You might have loved little Joe, but to me he was a kid; Adam was a MAN!
I had an innocent crush on "Adam" when I used to watch the show as a little girl. I remember thinking 'whatever happened to Adam?'. It wasn't until recently that I googled Pernell Roberts, and found out that he willingly left the show. I didn't know about the "Trapper John, MD" show until recently either. I wish I could have seen it.
I have seen Pernell Roberts in one Gunsmoke episode. I have a friend who saw him live on stage. I think he was in Camelot.
