blacktop/macadam

[Dale Coye]

I've been following this thread intermittently, forgive me if it's been
mentioned, but I used to be puzzled in Upstate NY by signs the highway dept.
would put up  "Road recently oiled"  which meant they'd put a new layer of
what we called "tar" down as far as I could tell.  Not sure what the "oil"
referred to.

The blacktop for us was a basketball court or other play area with blacktop
on it.
