The beach they go to has real sand, lots of it, with blankets and beachumbrellas, salt water, a refreshment stand, seagulls, dead crabs, sandbars, waves.
Lovely details include bottles of organic white peach juice in the fridge, jars of homemade wild blueberry jam, and canvas beach chairs and umbrellas--everything you need to do absolutely nothing in full-barrelled comfort.
