I just heard on the news this morning that some sick individual has painted a mural on a wall downtown near "ground zero" which is big and yellow and reads "caution: low flying planes"
I can't imagine what kind of jerk would do such a thing, and I completely fail to see the humor in it.
It is terrible to make such a mocking of the tragedy which happened.
I'm sure the city will be getting rid of it ASAP.
