Woke up early (as usual) to find a couple of whitetail deer browsing in the marsh below our campsite.
Broke camp, then headed over to the visitors center for a bit, then enjoyed a scenic drive on the Needles Highway - didn't stop as most of the turnouts were full of bikers. Made our way up to Mt Rushmore (more bikers) and did a hike around the base. Then made our way east to Badlands NP late in the afternoon. Drove the scenic drive with a few stops and camped at the east end of the park.
The kids completed another Jr Ranger badge and we took in a really neat astronomy program in the evening, though Jackson faded early so he and I went back to camp before the the real stargazing began (dark moonless night and a number of large reflector telescopes on hand).
