The Greenbelt is a great path to take to get across town on your bike, skates or on foot. Running along the river, it offers gorgeous views and a unique way in which to traverse town. But while much of it as runs between the treeline and the waterline, there's a funny stretch of it that parallels and runs close to Warm Springs Ave. A bit less green than the rest of the Greenbelt, it affords passing motorists a glimpse of serious bike commuters, recreational riders, two-wheeling families and, occasionally, someone on a pair of rollerblades for the first time. If, while driving by, you happen to see someone lose control and biff it, don't laugh. At least that person is out getting some fresh air.
