Boston Urban Adventures, Boston

Freewheeling around historic hallmarks and architecture, Boston By Segway, formerly Boston Gliders, has led more than 100,000 sightseers through Bean Town atop intuitive, easy-to-maneuver segways. Tours, which kick off every half-hour, range from one to two hours; the shorter version trundles down Boston's Harborwalk, and the longer sojourn ventures past historic hotspots including Faneuil Hall and Bunker Hill. To get acquainted with the segway, all upright rollers speed through a half-hour how-not-to-crash course, getting acquainted with the natural, fluid steering and learning how to propel the vehicle forward using a carrot tied to a stick. Armed with digital cameras, the urban sherpas snap shots throughout the tour for purchase afterward, and customers may take their own pictures as long as they briefly hop off the segway.
