In this thread, we will cover the campgrounds that are along the historical highways of the US and Canada. Among those that will be included here will be the old "Route 66" (former US-66), the National Highway, and also the Lincoln Highway. Later in the thread, scenic highways such as the Blue Ridge Parkway and the Beartooth Highway will be included.
The requirements to be included is that the campgrounds must be run by a public entity, such as a city, county, state, or even the national governments. It also is usually within a 20 mile drive of the major highway that is included. It also must either have its own website or be mentioned on more than one trustworthy website. If there is no website for the campground itself, there will be an annotation to "inquire locally". Sometimes that's the way to find an out of the way camping spot that is totally legal -- ask the locals.
