The first and only creation yielded by our summer vacation of 2005, we were only on the beach one day. The somewhat odd name comes from the fact that no one had any brilliant ideas as to what to build, so we all started building something and connected it all. The sand on Sand Beach (Acadia National Park, Maine) is decent, if slightly peculiar – a lot of it is ground up shell. It’s coarser and drains more quickly than some sand, but holds together OK if you’re patient. Repairs are a bit tricky.
