Like said above, the POI Factory is just filled with campgrounds and different kinds of campgrounds....Easy to add them to a Garmin and perhaps other GPS's. The only fly in the ointment is: the majority of the files are created by people like you and I. You may be very articulate in your quest for accuracy and insure the POI file you create and share is just nearly perfect....I, who isn't all that concerned with accuracy will create a file that is just kinda useful..sometimes giving you a POI that is miles from the actual location. But it may be in the same state. :) :)
