Segways add thrills to San Francisco sights

If walking or driving the streets of San Francisco is not quite enough adventure for you, try joining the growing number of people who are seeing Bay area sights while balancing on board a Segway, that two-wheeled electric vehicle that was once hailed as the future of all personal travel. Not only will you see tourist landmarks, but you'll learn a new skill and face just enough of a challenge to keep you, well...on your toes.
