We went to the beach after the Memorial Weekend crowds left. While walking on the beach we saw several sand castles in the tidal zone. Soon to be washed away.
A lot of time and effort went into creating these pieces of intricate art work. I'm sure that many people who visited the beach enjoyed seeing the sand castles. This casual trip to the beach documents that people will create without the expectation of ever getting paid. The fulfillment comes from the creativity itself.
