Do bring lots of water. Dehydration can make a great day not so great quickly. When you get thirsty, you are already getting dehydrated, so sip water frequently.
Do bring sunblock. A bad sunburn will ruin an otherwise enjoyable day.
Do bring some food, but be aware of foodborne illnesses and pack accordingly.
Do bring a Metro Farecard with sufficient balance on it to get home. Waiting in line at the end of the event is no fun.
Do report any suspicous activity to any police officer or uniformed National Park Service employee. We take all reports seriously and welcome the partnership with our community to make this a safe and enjoyable event.
Don't bring firearms, fireworks, alcoholic beverages, glass bottles, tents or other dangerous items. All people and packages are subject to examination to make this event safe for all of us.
Please don't bring your dog. While it is legal to bring your dog, dogs really don't enjoy being in the sun all day, and the fireworks will scare them. If you must bring your dog, it must be on a leash six feet or shorter.
Most of all, bring all your family and friends. There is a lot to do other than watching the fireworks. Make certain to visit the White House Visitor's Center for some special events. The National Mall also will host the Folk Life Festival.
