I am a mountain unicyclist from Philadelphia, Pa and I ride over at Wissahickon. Everytime I ride there, I consistently get told by mountain bikers that there is another unicyclist that rides down the other end of the trail…BUT I have yet to see or be able to contact him. From my investigations, it seems his Unicyclist.com name was gauss and he ended his posts by saying his name, Chris Wonderly. If you have a way of contacting him or know where the HECK he is, let me know! Please!!!
