Well, I took off this past Friday, in search of aragonite playsand. I went to Wal-Mart, 84 Lumber, Home Depot, some Rock and Tile place and did not find any playsand in the Charles Town area. I did find 5LBs at Gowers Feed, in C-Town, it is colored and a little over $3/5Lbs bag. I asked if they had other colors. They only had black but could get blue/white/red(I think). I got them to order me 25LBs of bluse and they offered me a 10% discount, so I took it.
On a side note, they have tropical fish, no SW. But had a good bit of stuff, even for cats/dogs horses and livestock.
On another side note, they were VERY helpful and VERY friendly!
