To add to my original post. Last week, Lorenzo Neal was at Hightopps on Monday night for the WNST radio show, Purple and Black Attack, giving free autographs. Fun show, and good conversation. He signed everything and even posed for pictures. The fans there had a good time.
The next night, he was at an AT&T store at White Marsh Mall. It cost money to get his autograph (I think) and the line was a good 100 people long and I doubt everyone got signatures.
Unless it is for a good cause, I'm not a big fan of places charging for autographs. If you are a fan, it should be about being a fan.
