The SuperMax link was kind of amusing-a 1995 speech by Senator Grams which ends up with a rant denouncing the high security at the US Capitol. Bet he regrets those words today.
BTW, I think there is also a federal prison in Indiana or Iowa that is also super-high security. I remember reading an article about it that said in its most secure area there aren't even mattresses-and the beds are concrete slabs jutting out from the wall. Probably reminds these guys of the home caves in Afganistan.
Unfortunately, I think all these high security prisoners are solitary confiement cases, so no chance of Bubba as a roomie.
