If you ever go to Omaha to planespot, head around to the north side of the field, along Lindbergh Plaza. There are a couple of parking lots to the northeast past the post office that you can sit and spot all day. I used to go there all the time when I lived there. Unless the winds call for it, calm wind runways are the 14s and 18, and that parking lot there puts you right next to the PAPIs for 14R.
EDIT: okay… I’m really going to date myself here, but who cares, eh? Okay… What ever happened to Adventureland in Des Moines? I last remember going to it in 1985, and had fun there, but don’t know what happened afterwards… and obviously it isn’t on Google Maps, but just to satisfy my curiosity… did they pave paradise and put up a parking lot, as the song goes?
