Hey, I was going to pipe in anyway and say to Mr. Neumann that the only thing better that I’d like to see in that picture would be Maxi Paws sticking up on those risers. I truly think that he should stop by there and offer to paint the cement holding up those risers green. And yes, on my property I have both cinder and pumice. Needless to say, it’s all around, and to top that off just several stone throws away from my place is the edge of a massive lava flow that’s part of a national monument. Clay in the Rogue Valley, Sildoc?
