the Springfield-Branson National Airport made the news for never towing roughly 25 abandoned cars. One car in particular was abandoned when the owner died... and the newspaper even published his obit. Some have sat there for 4 years

“At some point, we’ll tow them,” Boyd explained. “I don’t know what that timeline is. You don’t want to tow them or get them off the property too early because you know sure as heck as soon as you do that, somebody will show up looking for it.”
