Just thought I'd mention that this is their last catalog, and that you can only buy until 12/26. Then it's 'poof,' gone, another quality rock garden essential disappearing forever. I guess it's part of the makeup of a business based on a hobby rather than one based on a business plan to close when the hobby became too much work, but it hurts nonetheless.
