Caution

A yellow road sign, in the shape of a perfectly square diamond trimmed in black. Deer Crossing. Railroad Crossing. School Crossing.

These are the types of cautionary road signs I am accustomed to.

I know what these signs mean. Watch out for deer, or else you might hit one. Watch out for trains, or else one might hit you.

But, "Caution, Low Flying Planes" ?!?

Does this mean that as I return my rental car to the LaGuardia airport Avis station that I need to watch out for low flying planes or else one might actually hit me?!? Has a low flying airplane hit someone else in the past?

A low flying airplane?

Caution.

I think I'll rent a compact car next time I'm in town.
