Bitter Lake National Wildlife Refuge is a United States National Wildlife Refuge located in two separate sections in central Chaves County, New Mexico, United States, a few miles northeast of the city of Roswell. Both sections lie on the banks of the Pecos River. The refuge was established in 1937 to provide habitat for migratory birds such as the sandhill crane and the snow goose, but it is also notable for rare native fish and the over 90 species of dragonflies and damselflies that inhabit the refuge.

This one is definitely serious, incorporating a surprisingly good art collection for a small town, with works by Georgia O'Keeffe and Peter Hurd, among others. There is a wing devoted to space flight and rocket science (but not UFOs!) that includes the Robert H. Goddard Planetarium, named in honor of the rocketry pioneer who did much of his research in Roswell.
Devoted to the local cult activity; you can decide for yourself whether it's serious or not.
A state park with swimming, fishing, and hiking. The lakes are very deep with nearly vertical cliffs surrounding them.
