January
River Walk Mud Festival - To celebrate the annual draining of San Antonio's River Walk, a festival has surfaced with a parade and selection of the Mud King and Queen for the Mud Pie Ball. The festival has taken on somewhat of a Mardi Gras feel with crazy events, partying and a generally strange reason to have a weeklong party. The purpose of draining the river is to remove the debris that has gathered at the bottom which in the past has ranged from silverware to wedding rings.
