As much of the National Forest
roads\trails as available in the data source. FYI - some
roads that are legal are not on the map, and some illegal
roads are on the map. Verify your region via the
paper MVUM for accuracy.
Note: On most Garmin GPS units you can install multiple
maps and "layer" them over one another. This allows you to
install the Motorcycle tracks and turn them on an off if you are
an ATV user but wonder what the Motorcycle trail you just came
to is called.
