The Penngrove Social Firemen once again rev their engines and light their grills for the seventh annual Hot Rods & BBQ event this weekend. Bring your classic car, 1974 or older, to get in on the car show, or bring your family and marvel at the collection of roadsters on hand. There’s no entry fee for the cars and no judging—this is a pure and simple celebration of American originals. Live music will get the crowds grooving and the firemen’s famous barbecue chicken will hit the spot on Saturday, July 22, at Penngrove Park, 11800 Main St., Penngrove. 10am to 5pm. $5–$15. penngrovesocialfiremen.org.
