Next stop, Summit, SD - state number 3. This was 307 miles, a bit aggressive for us but was a pleasant drive. The campground (County Line Campground) was a one of our favorite stops. The camp hosts/owners were great and the site had all we could hope for. The town was tiny with not reasonable restaurant options but not an issue. Our schedule for getting to the eclipse was getting a bit tight so we departed the next morning.
Wildlife refuge with a large flock and water fowl (egrets maybe) that was stunning.
