The modern Segway far outclasses its early prototype, which was merely a tree stump with a saddle on it. Tour the ocean's coast in mobile, versatile fashion with today's Groupon: for $30, you get a one-hour Segway tour of Rockaway Beach and quarry from Silicon Segway (a $60 value), located in Pacifica. Riders must be 16 years or older and at least 100 pounds to ride; those under 18 must be accompanied by an adult.

Silicon Segway equips un-wheeled tourists with a Segway PT, which acts as an electric chariot that takes scenic-surveyors on a breezy tour of the coast. Pacifica tours start at 10 a.m. and 2 p.m. seven days a week. Civilian Robocops will gather at Rockaway Beach and don a fashionable helmet before cruising along the shores of Pacifica for a spectacle-filled hour. After a quick Segway training session, tourists can spot oceanic fauna while jetting through a wildlife area, then climb through 12 hairpin bends up Pacifica's Strawberry Hill. On the way, you'll encounter historic landmarks, ride past majestic bluffs, and perhaps even spot a whale popping up to ask, "Pardon me, is this the 5:19 to Scottsdale?"

Visitors to the Pacifica area can explore the scenic beaches and popular surfing spots or grab a quick lunch and stroll past the chic boutiques at the Rockaway Beach Plaza. Riders are encouraged to wear closed-toe shoes and to bring a poncho in case of inclement weather or dunk-tank accidents. Call ahead or book online to reserve your spot.
