My Garmin Map60CS makes finding an alternate route easy as well. Before leaving I load in the local mapsets for the area I plan on traveling in. A few weeks back I went to New Paltz NY to try a rail trail. We found the trail very boring. Used the maps on the GPS to get us back to our start via local roads. I had a paper map from a local toursit guide, but it didn't have the detail of the maps on my GPS, nor did it show my location on the map as I rode.
