There's a large, shallow, rectangular casting pond at the International Fly Tackle Dealer's show in Florida. I stare at it more than I use it. It's the show-off spot. That's where you go when your arm's on fire and you have a double haul you think deserves to be on display.
My arm rarely heats up in man-made conditions. I need fresh air to get the most out of my casting. There's no fresh air in a convention center no matter how high the a/c is cranked so I don't cast much at the show.
