Now in its fifth year, the KUHF Silent Film Series is one of the best free events in town. The series pairs a silent movie from the early 1900s with a Texas-based musical act that creates a score for the film and then performs it live during the screening. The films are shown on the lawn at Discovery Green, where large crowds bring blankets and pack picnic baskets to take in unique productions you won't see on the big screen anywhere else. Get there early to get a good spot, and hide your wine in a paper bag — everybody does it.
