Awww... no good deed goes unpunished. I was going to take some to Dallas when we went up there for you to use on top of your succulent pots. I don't remember why, other than I thought you were in Dallas and I was already taking some to a friend. You have no idea how hard it is to collect this stuff...every night drinking beer and wine, then smashing the bottles. I have my entire path behind the pond covered in glass....
