National Bicycle Touring Portrait Collection A SELECTED VIEWING Every summer we enjoy the parade of cycle-touring visitors who drop by our office here in Montana. These cyclists come from all over the world. Their variety of style, equipment, route, and purpose is endless. In 1982 Greg Siple began recording our visitors on film and asking them to tell their stories. Here is a small sampling of the nearly 3,000 portraits that make up the collection. © Copyright 1997-2008 Adventure Cycling Association.
