Plane spotting. I understand the appreciation of aviation and even hanging out at an airport once in while to observe the comings and goings...but I don't get those that take it to the level of commercial airport "plane spotting" as a descriptive hobby or even "profession"...I mean there is literally an app that tells you what the plane is and where it is coming and going. There is now a Youtube Live Stream of LAX so you can "Plane Spot" from the comfort of your parent's basement... I mean are there also people that stand on freeway overpasses and are like "ooooooh, a 4Runner, get a picture!"?
