Wood Play House

I just want to create about 5 rooms, so we can play paintball in my huge backyard.

How do you fix 4 pieces of wood along to stand so that we can cross them, and they used to fall so easily

if you just want a few walls you could book three 2x4 into the ground, which must hold a 4x8 sheet of plywood cut av in one side of the 2x4 and beat into the ground about 2 or 2 1 / 2 feet screws your board or whatever you use for the 2x4. You can make mazes rooms or just a wall to hide behind. must be stable enough to slam against them rather good, beat them flat. for additional support, run a 2x4 across the top of your corners angled .........> L

Heavy bolts or screws. Dr. bolts better. Be aware that you may be violating local building codes by this kind of thing, but that really cares
