Active travelers will be pleased to discover that Denver has the world's largest sporting-goods store--this five-story monster. With everything from footballs to golf clubs to tents, the selection is comprehensive. Extras include a driving cage for golfers, ball courts on the roof, and the annual Sniagrab (that's bargains spelled backwards), featuring rock-bottom prices on ski equipment every Labor Day weekend. There are also a number of Gart outlets in the Denver area.
