SALISBURY, MD - Parking lots throughout Wicomico County were crowded Friday as people got a head start on holiday weekend preparations despite temperatures in the 100s. Shoppers took to grocery stores for Independence Day barbecue essentials like hot dogs, hamburgers and water. "Definitely take tons of water and Gatorade, sunscreen, everything, because just standing here, it just sucks it out of you,” shopper Megan Short said.
