The Sweetwater Jaycees Rattlesnake Roundup is the town's famous annual oddity, held at the Nolan County Coliseum on the second full weekend in March. It is part wildlife spectacle, part county fair, and part old-fashioned Texas dare, with snake displays, contests, food, and a crowd that knows exactly what it came for.
This is not a quiet nature event, and sensitive travelers may want to read up before going. But as a piece of local culture it is hard to ignore: Sweetwater has turned the western diamondback rattlesnake into its calling card.
