according to the post i put couple days ago, has an article in it, that Yardright took oldcastle over. IT is YardRight
Tropical Play Sand now.
yardright has a list of Home depots that carry it, only a few.
they also have a contact on there website,
www.yardright.com that I am awaiting a response about where to get around here. When I get a response from them, I'll post it here as well. May arrange taking trip to the closest one and getting a bulk order if get enough interest and confirmed buyers.
Would have to be enough to cover the sand you're getting plus splitting gas.
