Plywood for bunkers in the SF Bay Area
Free: I have lots of large crates that are free for the asking in the SF Bay Area. You would be responsible for pick-up between 8:00 AM and 4:00 PM Monday thru Friday in the South San Francisco area. Right now I have three large partial crates, as well as the tops and one side to each crate. This stuff is usually 5 mm Baltic Ply (nice stuff, kinda a sin to waste on bunkers, but hey, if you have another use have at it...) and hardwood edges. There will be nails, staples, and stamped metal edges you would be responsible to remove.
I also generate large quantites of heavy (like 100#) pallets that might be decent barricades for a field. Again, youre responsible for carting, etc. I have a forklift to help you load it, but thats as far as I can go.
Please PM me if youre interested.
