This would be cook for crayfish boil! I think anything with built in cooler space is probably a good idea for summer. Kids wagon, outside seating, or this: DIY Patio Table With Built-In Beer/Wine Coolers.
American Flag Bottle Cap be really cute inside a wooden serving tray to use out on a patio for of July, Memorial Day, barbeques, etc. Great way to recycle the bottlecaps after drinking some :) or the best beer pong table ever.
