Kalkbreath, i think you lost it man. Are you sure you're fit to open a store cause from where i'm at, you seem clinically certifiable. I can just imagine you telling your customers to buy MI rock because it's radioactive. That will give your store a great reputation. Do you think the rock itself is 40 yrs old? I doubt most of it is over 20 and would not have incorporated radioacticity since. Seriously, think a little before you type and don't write anything you wouldn't say to one of your customers in your store. FWIW, you probably realize that your store is either gonna take off or bombshell w/ your little combo there, no need in jeopardizing it w/ kooky service and advice.
