Loon you are right.

In my opinion, the "Grand Tour" is an ambitious project for Harbour Lights. Something for every state in the lower 48.

There are pieces pictured on the map which have not been officially announced. These include:

Washington - Grays Harbor (From the Stamp Set Now as a regular LL)
Oregon - Umpqua River (From the Stamp Set Now as a regular LL)
Wisconsin - Pottawatomie (As a regular LL)
Virginia - Portsmouth LS Little Light
North Carolina - Roanoke River GLOW (first announced in 2007 as a 2008)
Minnesota - Two Rivers LL
Massachusetts - Chatham (as a regular Little Light)

So that leaves one each lights to come from:

Maine
New Hampshire
New Jersey
Pennsylvania
Indiana
Maryland
South Carolina
Georgia
Florida
Alabama
Louisiana
Texas
California

Could some of these be limited edition Little Lights for fund-raising?

Specific needs to be filled for 2008:

Collectors Society Gift
Collectors Society Exclusive
Christmas 2008
Store Event Exclusive (and matching thumbnail?)
Regional Event Exclusive

Speculations Welcome!
