What would be your first reaction if saw a bunch of teens running around a schoolyard with guns? Probably to dial 911, right?

But it would be different if you saw that guns were obviously brightly colored toys that shoot spongy bullets.

Novato Nerf Nation is a group of local teens who hold Nerf wars at local parks and schools. Chase Caligiuri and Davis Diercks serve as co-presidents of the club, which was started last year. They have a constitution and a rulebook.
