We have been lucky the 5 years we have been retired to take many bike/camp trips. Touring most of this country and part of Canada. But, the best adventure has to be that week in April 2010 we spent in the Grand Canyon National Park as it was really quite by accident. In planning the trip I had figured we weren't going to be able to bike during our time there, but as luck would have it the park had finished paving part of the South Rim Greenway. It's quite a ride and parts are quite close to the canyon edge..... long way down.
