Here are a couple of things you might want to bring next time you hit the beach: a swingball set, a volleyball net, a football, a frisbee and an industrial digger and a massive roll of fabric.
Why an industrial digger and a massive roll of fabric? Well, as you can see from this exceptionally fun video above, it turns out holding onto a giant roll of wet cloth as you're spun around and around and around by a Caterpiller 323D is really rather smile-enducing.
Our next suggestion? Taking bulldozers and getting them to dance for our pleasure on the sands. Can somebody get on this? Thanks awfully.
