"We may not have mountains, but we have [insert various local attractions here]." Kansas City politicians and boosters often utter this refrain as part of this city's chronic inferiority complex. The only way to pretend that Kansas City does have mountains is to pay a visit to the expanding Swope Park trail system. A sprawling mountain bike path there rivals the difficulty of some of Colorado's better-known single-track trails. And others are better suited to runners and dog-walkers. With the park's dense foliage, rolling hills and rocky surfaces, its trails are reasonable substitutes for terrains that Kansas City naturally lacks.
