Each year, over 30,000 people come to see the Patriots Point Fourth of July Blast (866/831-1720), featuring a hefty barrage of fireworks shot off the deck of the USS Yorktown moored on the Cooper River in the Patriots Point [1] complex. Food, live entertainment, and kids’ activities are also featured.
