I obviously have way to much time on my hands. In MS Streets & Trips I put in my home city as starting and destination points. Then in between I entered all of the US National Parks in the 48 States. Well I left out a couple offshore that I couldn't reach by RV. I scheduled two day stops at each park and an eight hour driving day.
Here's what I got: 44 parks traveling 15,000 miles in 91 days. There were only eight days that were layovers between parks.
Maybe I'll have to do this trip. Has anyone actually visited all of the National Parks?
If anyone is interested, send me an email firstname.lastname@example.org
and I will send you the route. You could easily change the hometown.
