The name pretty much says it all: BYOB, hop in a tube, and float down the San Marcos River. Meet up at The Iron Bear at 11am for a bus ride (to and from San Marcos), or meet at the river drop site. If you’re still down to rally at the end, there’s an afterparty at Rain on 4th.
Sun., July 18, 11am-6pm. $45-90.
