Fishkill
As a resident of Fishkill, New York, I can tell you that we got that call from PETA back in 1996:

We've got a lot of kills in this area; Peekskill, Wallkill, Sawkill, Deerkill to name a few. Turns out this area was settled by the Dutch and "kill" means "body of water". You know, where fish generally live.
