Im planning to build a new encloseure in my garrage for my black throats. Im going to use a 10' circular trough like pro exotics have built. Ill be useing radiant heat pannels for ambiant heat with a helix controling them. Ill be useing ceramic heat emitters for basking spots. Now to my question I have a good source for clean silty dirt that I use on all my monitors but I would love to try decomposed granite. The thing is I cannot find it anywhere. Does anyone know where I can find it within a hundred miles of Indianapolis. Thanks for your time. Ian
