And I don't care about format--worry about that later! I found some maps in Google maps, usually per state. I also have one map made my someone else, that no longer appears in the Google Maps search for user content. Maybe that user made it private, but I still can see it.
The reason I ask is related to my google maps navigation question on android.se. I think the easiest way to get this info on the droid is to create or use a shared map in Google Maps. I can find Florida, but no others show up.
Maybe it's a vocabulary issue? What else are are rest stops called?
