Mountain Biking
Mountain Biking has steadily grown as a sport in recent years. There are several different types of mountain biking. There is down-hill in which speeds can exceed 65mph, there is cross country which requires more endurance, there is stunt riding in which you have to have extremely good balance and know how to bounce your bike from place to place without putting your feet down or peddleing, and then there is up-hill, which requires traits from all three different catagories.  I have been mountain biking for about 4 years.  My favorite type is downhill.

Here are some Pictures.
