To answer Mum's questions...

Why would I go to Savannah?

It's on the way back up to Kentucky if we go via a different Highway.

It's also one of the prettiest historical places I have ever been.  They embrace their history and make sure that it stays instead of being torn down.  In fact they tore down a multi-level carpark downtown to re-establish one of their "lost-squares".

What's the significance of Waldo?

Waldo is the Canadian name for "Where's Wally".
