I was a goofy skateboarder, granted theres alot more to it than just being goofy or regular, but it took me a bit longer to progress than my regular friends. I think it has something to do with the tricks being devloped mostly by dudes who were regulars.
I was Goofy skating too, although I had several difficult tricks named after me - most notably was the "Gerry Facesave Cheevers", the "Crack the Vert(abrae)" and the infamous "Hind Grind". No doubt you've heard of them. You're welcome in advance.
