Looking at this picture, its not a very pretty scene is it. To me that is a view of fun. What you're looking at is a section of the Schuylkill River Trail in Conshohocken PA.
This trail runs roughly from the Art Museum in Center City Philadelphia at the Rocky Steps for 22 miles out through Conshohocken, Norristown, and Valley Forge to the Perkiomen Creek Trail in Montgomery County, PA. I skated that trail for about 10 years, and a total of over 20,000 miles to date.
The trail is continuous through the length and is a jewel for the region. I was fortunate enough to be close enough to skate a segment of it whenever I wished. No cars, few intersections to worry about, very few bad spots with gravel. This was 22 miles of Black Ice. There were a few rough spots where there was a sharp incline or a curve, and one hill in particular that was at a railroad style incline for about a mile. That was my definition of fun, skating down that over 15 miles per hour with some Armin van Buuren "A State of Trance" podcast DJ set running on the head phones on a clear crisp day with little wind.
One of the days when I get back to Philadelphia, my plans are to drive back to my old parking area and skate this section again. The trails here are nowhere near as long and comprehensive as this. The best one I've found in Broward County was at Pompano Airpark and that one is only a 5 mile loop. Every time I get a chance to speak with someone in command of a Parks and Recreation budget I put my two cents in for a "multipurpose asphalt paved trail of a minimum length of a mile". Why not? It's worth your life here to try to cross the street on foot let alone on Rollerblades 8 or 10 wheels.
