PyZahl hates littering on bike paths

PyZahl was just out and around the corner of the nice and clean neighborhood north of the laboratory as a sudden gentle hissing from the rear wheel changes his good moods at the end of that great day...

The cause was located quickly....


He hates if people are recklessly throwing glas beer bottles (this seams to be the most common and most cyclists unfriendly) on the roads... and then little pieces eventually find there way like shown here.

Not to say, that this cut has destroyed some of the threads and thus the tire for further reliable use :-(
