yeah--
skating (or snowboarding) regular foot or goofy foot has little to do with being right handed or left.
i skateboarded and snowboarded for 15 years or so and peoples stance is prob half and half... while the population is much more right-handed i think. its just whatever feels right when you first start.
then theres the whole "sh_t-foot" or "d_ck-footed" but thats just some thing different entirely.
