Unfortunately, the Sacramento River that did so much to put the city on the map also had the alarming habit of flooding on a regular basis. The early town was practically erased several times before levees and the Yolo Bypass were built. The Causeway, a section of Interstate 80 on stilts, crosses the Yolo Bypass and connects downtown Sacramento with Davis. The University of California, Davis, attracts thousands of students and faculty with a taste for non-mainstream entertainment. Most evenings, the downtown streets overflow with townsfolk seeking unique events such as poetry readings, live theater, gallery openings and music concerts.
