Not applicable to this thread, but I was in David's neck of the woods yesterday (hockey game last night and SWMBO wanted to shop first). I had my opportunity to go into my first woodworking store ever, which was the Rockler near Ross Park Mall. They only had one stone, so someone in that store must be reading this thread (although that stone was a two side, fine/coarse manmade thing).

In all fairness, it was nice spending time in a store catering to woodworkers and I enjoyed looking at the wide array of turning stock and other items on display.
