Allow users to enter historic data, so while driving by a landmark historic information or links to historic information could come up. There's an untapped gold mine of local information that could highlight an otherwise hum drum drive. Ex: On this site the KKK used to hold their local meetings, or the dirt road leading off to your left was the site of the original post road, or the run down buildings on the side of the road were once Stage Coach inns, circa 1865, etc.
