I Just came back from a cycle tour of the Italian Dolomites. I have always felt a kinship with cyclists be they MTBers, Roadies, tourers, until now.
Going over those mountain passes, these "purists" think they are in the Giro d'Italia. At every pass, (highest point across the mountain) the roads were littered with gel packs, energy bar wrappers and other such trash only a cyclist would leave. It was disgusting.
Never again will I feel any camaraderie for these people who feel great about themselves, bringing their crap uphill, but are too tired or concentrated to bring the wrappers downhill.

Next will come the video cameras and recordings to send to the authorities
