Ash Wednesday is upon us, which calls for a little known celebration called Fat Tuesday. The Norman Mardi Gras Parade starts at 7 p.m. Saturday, March 1, in downtown Norman. Under the theme “Come Together,” the parade’s 20th annual march also celebrates Beatlemania. Look for bright, fun floats, the Zydeco All-Stars, DJ Gumboman, the Boyd St. Brass Band and more (www.normanmardigrasparade.com). Tulsa lets the good times roll at 7 p.m. Tuesday, March 4, in downtown Tulsa’s Blue Dome District. The parade is for all ages. Look for district restaurants, merchants and establishments to celebrate following the parade.
