Nice site.
I’ve been on one of those roads. I was on US 219 in western Maryland, on my way to visit the Fairfax Stone, which marks the headwaters of the Potomac River. As I recall, I saw very few other cars on the road. And I was the only visitor at the Fairfax Stone park in the middle of a summer day. I know it’s not a huge tourist attraction, but still I thought it odd, I was the only person there.
I had the same feeling when I was the only one visiting the Coleto Creek battlefield in Fannin, Texas. Although the Alamo in San Antonio gets about three million visitors a year, the site of the Coleto Creek battle, a Texas Revolution defeat which cost the lives of more than twice as many Texans as the Alamo, apparently gets few visitors.
