If you guys are planning on going anywhere near public or private campgrounds, state parks where reservations can be made, etc., you are a year too late. I've been reading on other forums where public campgrounds across the country have been booked full with waiting lists since January 2016. Even dispersed campgrounds, deserts, etc., will probably be crowded more than the 4th of July, especially if they are in areas where cloud cover is almost guaranteed. A group I was reading about was trying to get campground reservations in very rural Wyoming, far from the the national parks, and could only get six of their group in one campground and two in another. And this was late in 2015.
Closest to me is 6-7 hours south in southwestern Kentucky or southern Tennessee. Lots of detailed information on the
Great American Eclipse web site.
Something exciting that I did find, is that although it has been 38 years since the last total solar eclipse transited the USA, the next one is on only 7 years, on April 8, 2024. Better yet, is that the center of the path passes within two miles of my house, and the length of greatest totality is 3:54 vs the 2:40 this time around. I sure hope those April Showers aren't happening then!!
