several hundred holds, several hundred EXTRA T-nuts and bolts.
Over 300 square foot cave with 8x8 foot roof, 8x12 foot 55 degree overhang, 2 8x10 foot vertical walls with a big long bulge on one side. Built with 3/4 inch plywood with 2x6 support beams throughout (independant and rock solid). I'm moving to AZ and there's enough rock and sunny weather that it would be stupid to haul it down there. So the best offer carts it away. I'll dismantle it.
