Thanks Matt, I looked in your gallery at your rock, you can't tell it's diy. this months (Aug) issue of FAMA and it had an article on diy rock. After reading it, it did make me think a little bit about the environment.
It also made me think that I could save some $$$ because several hundred lbs. of rock will cost some serious bucks.
Also, if anybody has made some, let us know about it please.
