I'm lookin for some SouthDown in the southern miami area, i'm willing to travel about 200miles or so for some.. if there are any local stores that carry can you please help me out? i've checked 3 or 4 HD's in the area but to no luck but i did find a very white play sand.. i've read some posts on silica sands and this one was very white.. It wasn't quickcrete but something else, it started with a "B" anyone? thanks!
