Wait two holidays???

With the 4th landing on a Sunday it seems that Saturday - Monday have become the extended holiday. Brian camped out with the boys and built a fire in the evening so we could light the fire works. He showed the boys the proper way to build a fire with gasoline!#$%^&$%$ Really? I don't understand that, he said "they are going to do it I might as well show them how to do it with out getting hurt!" I reminded him that our boys are 8,6, and almost 5! I think we should have just went with NO YOU CAN'T build a fire until you are 21!
