[Psalm 73]

"....WWII battleships or aircraft carriers that are on display around the country, looking at the boiler rooms is fun."

I'm a "propulsion guy" too - have seen the Midway (San Diego) and the Lexngton (Corpus Christie) - boiler rooms a sight to behold.
Hoover Dam turbines (pre- 911) was fun to see, too.

[Arthur McGowan]

You’re not allowed to see the innards at Hoover Dam?

I’ll know we have returned to sanity when the sign says: “Hourly Tours for Non-Muslims.”
