Walking around northwest Denver today, there was plenty of snow melting.  At first I was concentrating on some images of the difference since yesterday, however walking back to gallery nrc I passed by the Pearl Velo bicycle shop and noticed part of a bicycle sitting outside.  With just the frame, crankshaft and chain, it was quite interesting. After a few images, I took an image of the chain which is the image for Day 3 of Thirty Days 2011.
