There was a time when we had our own paintball field. It was local for all of us. About 5-10 minutes away for everyone who wanted to come and play. We didnt charge anyone. As long as people brought their own paint and air, or a few bucks to put towards refilling our scuba tank, we were good.
We scoured the neighborhood, looking for pallets, tires, and wooden wire spools from the electric company. We made it work. We played about every weekend up there. IIRC, we had a fire pit and camping area as well.
It's too bad the land was sold. We were blindsided one day when the new owner left a note for us under a grill cover on our picnic table.
