BIG CRUISEFEST IN THE ROCK10 a.m., River Market. Free.
Grease monkeys, hot-rodders, low-riders, motor heads and general car enthusiasts, take note. Cruisefest returns to the Rivermarket on Friday and Saturday with a wide slate of tricked out talent. Perhaps the most legendary custom car creator, George Barris, “the king of kustomizers,” who built the Batmobile and the Muster Koach for TV, will be on hand. So, too, will Norm Grabowski, famous for creating the T-bucket hot rod. One of the last cars NASCAR hero Davey Allison drove, a 1993 Busch Series Chevrolet Lumina, will be on display. Plus, the Texas Bandit, a low-riding truck that spews flames; a NASCAR simulator; Lightning McQueen from “Cars” and Kitt from “Knight Rider” come to life. On Saturday, if your kids or significant other grows weary of cars, there's water bowling, an adult tricycle race and costumed heroes (Superman, Darth Vader, Elmo). And, from 2:30 p.m. until 5:30 p.m., the local cover band CRISIS performs.
