So what practical ideas do you guys have for building field fortifications? Nothing ridiculously expensive or difficult please(eg. underground bunkers, used airplanes, train cars, ect.). Even though I would LOVE to have cool stuff like that, in all likelyhood we can't get those for our field, so.
I was thinking things that are durable, inexpensive, wind-resistant, and look cool. And stuff needs to be preferably wooden, or something we can at least burn should we need to break down our field.
A few ideas we've had recently are sheaves of sticks or brush tied around stakes in the ground, and sandbags. But we need lots more ideas!
We already have some things like tires and wooden wire spools on our field. And afew places built in sinkholes and trees.
