Leadville and Lake County raised nearly a million dollars over the past five years to overhaul Huck Finn Park, adding tennis courts, an ice-skating rink and one hell of a skate park. The 21,000-square-foot concrete arena was built by Native Skateparks with help from a $350,000 grant from Great Outdoors Colorado (your lottery dollars at work) and sources as diverse as the Tony Hawk Foundation, Leadville Elks Lodge #236 and the Climax Molybdenum mining company's charity golf tournament. The park features a huge left-hand kidney bowl that goes from six feet in the shallow end to nine feet in the deep end; an 8,000-square-foot flow-bowl section; and a straightforward but well-designed street section. Pro tip: Bring plenty of water and sunscreen, because you'll be feeling the 10,200-foot elevation as soon as you start skating.
