i rode through a campground the other day on my track bike. was looking for a place to take some pictures of dirty bikes. it was pretty fun up until i buried my front wheel over the 60mm presta valve stem in mud. tried quickly to push out with a hard pedalstroke and only spun the back wheel. damn those pizzacutter wheels! almost fell over unclipping, and had to uncake my fork steerer of mud after i returned home and bathed her.. other than that, it was a blast!
