The next day, we lounged around our campground at Big Bone Lick State Park. That involved sleeping in, reading at the camp site, swimming, and visiting the museum at the campground which boasts many fossils, salt / mineral springs, and a bison herd.
On the way back, since we had about 2 hours to do it, we stopped at the Wright Patterson Air Force Museum in Dayton, Ohio and walked through a few of the hangars. The museum is free, and it would have been nicer to spend a few more hours there, but as the schedule demanded, we got back on the road to get home by Thursday evening.
Here are some photos from the trip. Enjoy.
