Admit it. Ever since you saw Dogtown and Z-Boys, you’ve been wanting to try skateboarding, but you’re worried you’ll (a) look like a midlife crisis waiting to happen, (b) get laughed at by teenagers, or (c) hurt yourself really badly. It’s not too late to learn, though, and the right equipment will help mitigate most of those concerns. KCDC Skateshop (90 N. 11th St., nr. Wythe Ave., Williamsburg, Brooklyn; 718-387-9006) builds a perfect beginner’s board. It starts with a tough deck from 5Boro, atop some large and forgiving Pig cruiser wheels mounted on nimble Tracker RT-S trucks (the axles), and you’re mobile for $125.99.
