This week, I read in the paper about the Airport Authority's effort to remove the squatters from the area and reclaim the land as their property. The next time I drove by, I saw this banner, stating roughly the same.
Its a difficult, complex situation. On the one hand, the Airport is right. Its their property, and it is really important to re-establish property rights as part of a proper, rule-of-law environment.
On the other hand, this dusty little spot is one of the few public recreation spots in the whole city, and it is very prominently situated along the main road into town (it is even mentioned in a New York Times article about Hilary Clinton's visit). I just wish that the place could remain as it is (and by that I mean have a significant investment to make it a true public park), rather than reverting to the domain of the airport authority, where it will likely not be as publicly used as it is in its current state.
