You're going to have a hard time competing with Steve's "Hangar Queens", but
I'll see if I can spot it!

If you can't find an airplane for your roof, Jay, there's a big cow
(about four times life size) on the roof of a restaurant near here
that just changed hands; perhaps the new owner would let it go cheap.

Can't think of an aviation connection, but it IS eye-catching!
