You don’t have to look out the window for robins hopping gravely around in the backyard; TV has its own rites of spring. This week MTV travels once again to Daytona Beach for its three-day boogie ‘n’ babes bacchanalia, Spring Break ’92. The lost weekend begins Friday (March 20, 3 P.M. ET). Farther south, ESPN has its first Grapefruit League baseball game on Saturday afternoon (March 21, 1 P.M. ET) as the champion Minnesota Twins take on the Pittsburgh Pirates in Fort Myers, Fla. Only two weeks to opening day, sports fans.
