In a big city like Austin, there are several different tours offered to see exciting parts of the city. You can take a segway tour around the Capital, a Ghost and Bat segway tour, bar hopping tours, even a water-to-land tour (Austin Duck Adventures.)
Most people think of riding a bike as just a leisurely activity. Some do it for sport (like when you see the pack of cyclists riding on the side of the road, training for the next ride.) But a lot of people don't know much about the health benefits cycling actually provides.
