Hate to be obvious, but as the city boasts, the Denver Skatepark is the largest free public skate facility in the nation. With over 50,000 square feet full of planters, curbs, rails and a half-pipe, the park was envisioned and designed as a way to lure away the hordes of young skaters who descended on the 16th Street Mall and other city streets every day looking for a fee-free place to grind. It's lit, so the park is open from 5 a.m. until 11 p.m. every day of the year. Heck, someone else might even cite it at the next HUD gathering: Best Solution to an Urban Problem That Has Actually Worked.
