I made the table below to help making maps for TooFatLardies Dawns & Departures scenario generator. I posted it to the TFL Sharp Practice forum using photobucket. The url for the forum is http://toofatlardies.co.uk/forum/viewtopic.php?f=31&t=4929&start=20
Evidently that use if not allowed by PhotoBucket so I am posting it here instead. If you find it useful let me know.
