As has been mentioned earlier on this thread, there is a G13 in eastern
North Carolina along the barrier islands.

There was a Green airway based on the Galveston NDB that was
decommissioned within the last 3 years (the airway, not the NDB). I am
not sure if it was the last one or not.. but it ran across the Gulf to Fl.

From what I've been able to find, I gather that these aren't in use in
the
US anymore, and haven't been for some time. Seems they're still used in
Canada though, and are still mentioned in the FAR's. Something to do
with
L/MF navigation, but I don't know what that is.
Heck, I can't even find mention of them on Gene's site, so they MUST be
long
forgotten. 
Someone please give me a history lesson here. Thanks.
