Mounds of sand line the B Street Pier along San Diego's Embarcadero, just waiting for a sand sculptor to get inspired.
The delivery of 300 tons of sand for this weekend's U.S. Sand Sculpting Challenge took more than a dozen truckloads, according to organizers.
The event kicks off Friday, Sept. 2 is one of our Things to Do This Labor Day Weekend.
San Diegans can stroll along the pier and watch the sandcastles gradually appear.
Or, for the very-curious, a professional sculptor will talk at 2 p.m. Monday about how to build and create a masterpiece on your next visit to the beach.
