True.
TPBM has toured Hoover Dam.
[I'd like to comment on speaking "Tennesseean" - true story;
While boarding one early morning flight from Chicago to Washington DC, the captain had the cockpit door open, and looking back, picked up the mic and said:
"Morning, you all. In case you have trouble understanding me, it's because I'm from Noath Car'lina; but don't worry, the copilot is bilingual and can translate. I have to say you all look fine this morning. Back where I come from, there are only two reasons to be dressed so fine this early in the day. Either you are goin' to church, or you are just coming in from a night of carousing - and somehow, I don't think you all are on your way to church!"]
