Winter Gunk
I took these 2 on my Thursday afternoon ride after school was let out early. The first is from the restroom of Seneca Park, the second along the footbridge in Cherokee. The key feature is the amount of crud which accumulated in the bottom bracket and seatstay bridge areas. Once it started to freeze it was like riding on a trainer or something, with my own bike providing resistance. Wet.

On a bike with fenders I've had the space between the tire and fender build up with gunk. Once that happens it's like pedaling uphill into a 40 mph headwind.
