I generally don't feel inclined to review airports, because it's the equivalent to going to the dentist for me. With the unavoidable--"Sir, we're going to have to check your bag"--routine that my camera gear brings forth, I fail to see the joy of an airport.
The slot machines at Vegas's airport, however, never seem to fail mesmerizing me. Watching people constantly go broke before boarding a plane is nothing short of brilliant. That last fix before heading out of town; it's marvelous.
My favorite part, however, is taking off the runway and seeing the strip. As ridiculous as I think the strip is--I still think it's an amazing sight and moreso from an ascending airstrip.
