asheville has a more tranny based concrete public park, Food Lion Skate Park. there is also a foundation DIY spot there. you should go to Push Skate Shop, those guys rule. tell em youre from out of town and they'll take care of you. Hendersonville is about an hour-ish away and is a really sick concrete park, more street oriented and no pads/helmet.
if youre in Charlotte hit me up!
