The grid has already been on the internet. I saw a piece on cable news where a grad student's thesis was classified because he'd written a "how to" paper on the various US grids, complete with diagrams. Since that time I understand much of this info has been pulled (this from the Army Corps of Engineers)...but it's been out there for quite some time.
