I've called the two HDs in Manhattan (23rd and 59th) and the "operators" had a tough time understanding what play sand was, immediately insisting they'd never have something like that there! Does anyone have a SKU number from an old bag somewhere?
The SKU will bring up "playsand" whether it's the right stuff or not. You're better off going to the one in queens or bkln and looking in the garden dept.
They stopped collecting the Caribbean sand. Sorry but It's not gonna be available for a long while.
ESV is gonna have a new sand out its calcium carbonate based and it's white like really white. I got and advanced bucket of it. It's really cool.
