"Jungle Queen" Steve, this was my second PAGG and the first time to go for the full weekend. I think one thing that was really cool for newbies or those getting back into pinball is the 'school' where people taught folks how to play pinball.
I know some friends who 'taught' and got a lot out of it and also met some folks who took the class and said they learned a ton even though they've played pinball for years. I think that's a great ambassadorial thing and maybe could be expanded to more than just Sunday (or did it already happen on other days too?)
