I'd like to be able to take the US map and have a virtual RAGBRAI with my other cycling buddies, but you can only map one route at a time per map. The whole Google idea is collaboration. I'd like to be able to share a map and editing capabilities. I'd like to be able to have different color-coded routes, so that friends could pick a color and start mapping. As the season wears on, we could see who gets to the West coast first.
