Road Sign Typos

On the way home from our Easter visiting on Sunday evening, I noticed some interesting signs on the interstate. We were traveling through a stretch of construction, where most of the permanent road signs have been removed and replaced with some temporary signs. Apparently the temporary signs were not proofed all that well. They read:

"North Chicago Navel Station"

and

"Campbell Reginal Airport"

I know there was a third one, but I cannot remember what it said. So, if you're traveling on I-94 North in the far northern suburbs of Chicago, check out the road signs between Rt-60 and Rt-120.
