Shasta Glide 'n Ride's tour guides time their running commentary, broadcast through headsets, to the whir of Segway wheels propelling patrons through scenic stretches of the paved Sacramento River Trail. First, riders hone Segway skills during a brief session that includes hands-on training, an instructional video, and tips on how to garner the best mechanical performance by impersonating a mother robot. With new Segway knowledge in hand, tours embark from the parking lot at Turtle Bay Exploration Park. Roadsters obediently bend to their riders’ whims as they zoom across the nearby Sundial Bridge and through sunning flocks of wildlife to the tune of tales about the Gold Rush and Old West. Available cooling vests enable comfortable treks, even on days with 100-degree temperatures or hot-cocoa downpours, and modern technology allows Segways to slice through fog or light rain. Patrons can also design their own tours atop rental bikes and pedal through local flora and fauna for hours at a time.
