We really aren't into visiting battlefields. Generally, they are macabre, empty fields with little to look at and much to get depressed about. But Little Bighorn Battlefield National Monument has some striking points of interest and, frankly, we were driving right by.
Bozeman, Montana has dinosaurs. The museum of the Rockies is where you find them. Compare T. rex skulls and the transition between an adolescent Triceratops to an adult. See paleontology in action at the show lab where paleontologists are absorbed in cleaning, preparing, and analyzing new fossil discoveries. My favorite curatorial flourish is the partial sculptures where half is a fully fleshed dinosaur with the other side being the bones in situ.
