i was wondering what the general opinion of pump tracks is? Pump tracks are great skill builders, tons of fun, and safe! http://www.youtube.com/watch?v=fofuwA2iOfE here's a link of a guy riding a pump track, to save some description, if you don't know what they are. I think we should have one here! from what i've read and seen on videos like this, pump tracks can be built in small areas, such as backyards, but good ones usually take up about 60' square, still pretty small. I'm not very familiar with the rules of trailbuilding at sunderbruch, but it seems like there would be space for one there if building one is allowed. i think this cycling community needs a good pump track. what do you guys think?
