My CFII tried to get me to do this at least once that I recall. An offset
LDA actually pointed towards the "wrong" airport (somewhere in Connecticut,
I think), or something like that. The "wrong" airport is closed, so the
'X' marks are a hint in that case.

There's also a river between the two airports which - if the pilot is paying
attention - would also serve as a hint to a pilot paying attention.
