The Wench and this ol' pirate had solved the Local Geodyssey and picked up the final, but ridiculously became stuck finding the TB password. Seems I was using a wrong set of coords. Once I changed to a different set, I could see the lights. Maybe I spent too much time wishing I was laying on the stars looking at the sand, than really laying on the sand and looking at the stars.
Thanks for the discovery, it was really puzzling. YO HO, YO HO
Now only the Hidden Challenge to finish up to find the last TB.
