Might have to go a bit out of your way. South Carolina sells fireworks all year. Myrtle Beach allows fireworks on the beach year round. There are a number of campgrounds located on/near the beach. We just returned from Ocean Lakes where our dogs were terrorized well into the night by big stuff being shot off.
