Interesting comment about airplane baggage..
I wonder if this still holds true in our Post-9/11 world. It might have been OK Pre-9/11, but in a Post-9/11 world, I'd bet that it would draw some suspicion from your Post-9/11 airport security or Post-9/11 baggage handlers.
Truth is, in a Post-9/11 world, things are different, in a Post-9/11 kind of way. In a Pre-9/11 world, you could have connected a Pre-9/11 short across your Pre-9/11 battery, and caused a very Post-9/11 type explosion and rupture of the battery's Pre-9/11 case.
But in a Post-9/11 world, who knows. People are more on Post-9/11 edge than they used to be, Pre-9/11.
Anyway, I need to click the 'post' button now, to post these Post vs. Pre-9/11 comments.
