If the weather this weekend forces you indoors, the IMAX theater at Marbles in downtown Raleigh is an excellent place to head for some entertainment. They have several features playing now that are 3D, including the highly anticipated Iron Man 3. There are some other fantastic nature features that are great for the whole family, and educational to boot! Check out the full schedule here, and plan some extra time to take your kids over to Marbles for some added fun.
