I designed the cart for hauling sand but as soon as I started building the sculpture I went for a load of water. Moving four buckets per load rather than two is a big improvement in itself. Time is precious.
Here we have the design purpose. This cart works even better than I imagined; this is the way of good tools. The photo was shot on the cart's second outing, when I was hauling sand 200 feet from borrow pit to building site. It was no problem.
