Hello from Hero Dad*, i'd like to give you some simple tips on how to throw a rockin' Nerf gun birthday party. Essentially you just need to transform your backyard into a Nerf battlefield and the kids will do the rest. This is a sure fire way to have tons of fun at your next birthday party (ideal age is 6 to 12) for not much money (although there is a bit of work involved) using some easy to build Nerf games and Nerf battle modular forts.
*Hero Dad defined: any dad trying to impress his kids with some type of act or service
Lots of card board boxes (the bigger the better) I used 48x24x24
sharp razor blade or box knife
spray paint for camo
