Sweet pics!
Years ago when the wife and I toured the Jack Daniel distillery in Tennessee - the tour guide took us through areas where photography wasn't allowed. I figured it had something to do with manufacturing/trade secrets. But in fact - the alcohol fumes in the air were highly combustible...so they didn't allow '
flash photography'.
Luckily, I had lugged my tripod along...and was able to get a few good interesting shots (without flash) in areas where most people weren't able to take pics.
