With its 30-degree road grades, mean-spirited bicyclists, and assortment of homeless pranksters who make a vocation of scaring the bejeezus out of tourists (think Bush Man), San Francisco isn't always the most pedestrian-friendly big city. So why walk when you can, um ... what do they call it when you ride a Segway? You'll find out soon enough with Electric Tour Company, a Fisherman's Wharf–based outfit that offers tours of the waterfront aboard your own Segway Personal Transporter. At $70 for 45 minutes of training and a two-hour ride, the tours are middling pricey, but worth it — Segways are fun as hell, and once you're mounted up, those aggro bicyclists will have no choice but to make way.
