Cow Bay is an area of Long Island and is about 90 minutes from me. There used to be a sand mine there that supplied NYC and Westchester County with sand for years and years but from my research has seemed to have been retired. Most of Long Island is beach sand and I'm hoping there are still mines in operation out there. The sand local to me packs almost instantly and isn't suitable. There's no way I can afford to pay the freight on sand from the southern US, I'm cringing at what it will cost to come from Long Island!!
