Calling all racing enthusiasts and their “pit crews”: Bricks and Minifigs, the LEGO store in Manahawkin, hosts a “free build” event this Sunday (and the third Sunday of each month) from 11 a.m. to 1 p.m. Arrive early to get first crack at the limited supply of parts to build a race car and race on the derby track. The idea is to build with LEGO bricks without any specific instructions.
