LOL! What tanks? Nobody said anything about tanks.
You may want to look a little further into this subject prior to dismissing everyone. Perhaps take a ride to Fayette County SO, where they have a tank. Perhaps you could go visit Walking Small, Sheriff Victor Hill in Clayton County where, yes, they have a tank. Those are the two that I know of off of the top of my head. I'm sure there are more. LOL, indeed, sir.
