Hey guys:
A quick tip:
There is a massive collection of truly professional pictures of the 2013 Philly ride on Flickr, just use the search term "PNBR" for Philly Naked Bike Ride.
The pictures were taken by a real pro, Nathan R., and he obviously has both a great eye and super quick reflexes because he captured so many great shots. He also managed to find, and focus in on, some fully nude female riders that seemed to have escaped other lenses.
The pictures are all watermarked, so none can be posted here, but the collection should not be missed.
Nathan R. nailed it.
See for yourselves. Flickr.com then search: PNBR
