I think (know) they are from Texas. And all things in Texas are good, right?
Well, heck y'all, there's no reason to be shy, here is their site: http://www.soilmender.com/index.html
I also think their site could be better by at least having a list of dealers (like TX Dealer maybe) and available outlets and more content information, ratios & standard analysis on all products not just Yum Yum, prospective dealer info, photos of product instead of just bags, before and after photos, and did I mention "more content".
I do like the link to Texas Recylcing (although it ought to be in a target frame) where I found a list of TX compost and related producers. http://www.texasrecycled.org/landscaping.html
