Where oh Where is "The Grand"?

Is it in that little park by the dairy store?
Is is down the road at the "twin bridges" by the dam?
Or off on a side road at some little out of the way nature center?
Perhaps the "certificate" hasn't even been created and folded in such a manner to fit in the magnetic key case Mark Brady uses to protect it from the weather.

So far, only the "Keeper of the Clues" knows for sure.
