Well I might make a field in my friends ofrst... but everything we make will have to be movable (like a 5 min walk). So what type of bunkers would be any good for this. It's a tight area too bt, tons of trees.
im building a field in the woods behind my house, my nieghbors who own the woods said they dont mind as long as no paint gets on their house, lol. anyway, im building bunkers from logs and rocks and digging foxholes and trenches, it'll be like sumthing out of ww2, lol
