18 cinder blocks and 18 slabs, angle iron from lowe's, and countless tubes of Loctite construction adhesive and liquid nails. It cost me about 80 dollars and took an hour and a half to build. It's higher than it looks from this angle.
Can't wait to build more stuff! Unfortunately, with the scene around here, everyone is all talk and no show. Several people said they'd pitch in money and help me build it. That never happened. But guess what? They sure skate it...
