A recreation that is characterized by the inability to bail out (as in skateboarding) or brake (as in bicycling). This makes even routine rolling an extreme sport unless there are no hills or traffic.
Stylistically, it is possible to be as dashing as Mercury, the winged-foot messenger god. However skaters are usually squatting and flailing their arms as they try to balance, so they end up looking pretty flamboyant.
Athletically, you can go for speed, skateboard style tricks, or dance moves with cones (slalom). Unless you have flat wide space, survival is usually challenge enough.
When rollerblading, always choose a route with no stop signs at the bottom of hills. And whatever you do, don't bend at the waist and flail your arms in circles like a complete fruit.
