I have family that lives in PA and NJ (where I have heard that it is easier to get). I am planning on making a couple of trips up there this summer and fall and might be able to bring back a bunch if I can locate some (I'll take orders from MTRC folks once I find a supplier and figure out the exact dates of my trips). My problem is that I have read stuff about name changes all over the place and I don't really know for sure what the name of the sand is that I should be looking for. In addition to Yardright Tropical Play Sand, I've heard that it goes by the name Old Castle and some other one I can't remember. It seems like it wouldn't matter as long as it is aragonite and clean, but I don't want to buy a few hundred pounds of the stuff, drive it 800 miles in my car, and then find out that it can't be used.
