Now that I have managed to get out of my kokkenelli haze from the hols and then managed to get myself dragged out of fuel tanks I have found your little secret, Tonkers.
I could not for the life of me remember the name of the place but after looking around most of Sandland finally gotch ya. (What a stupid name for a place)!
Not too far from TCs and the Diplomat, as the crow flys.
Never had a GE's wallet. It was always empty when I got back but I always had a smile on my face
Took me less than an hour of searching
Pretty pleased with that I must say!
Obviously I started out looking too far north but after leaving that cold trail and by using Google a bit more productively I found the answer to your challenge Tonks. Good one!
