These were a huge help on our trips along the parkway. No signal for most of that area.
the roads are color coded for good, medium, and not good riding roads.
The back has info about gas stations, hotels, descriptions of the roads, etc. Well worth the money. There are 7 in this set, and a handful of other broader area maps made specifically for Motorcycle touring.
+10 Amanda for finding and buying them last year before the first trip.
