Wow, that is risky! Was the slight bow in the horizontal beam intentional or is it due to carrying the weight of the spear-people?

I think it was intentional - that beam was very think as they were walking on it and standing on it to make the spear=people. But as the vertical pieces were finished they went to town sanding that horizontal piece into that bow shape. It was pretty awesome to be next to, The germans made margaritas for us when it was all done!
