Tell es-Safi in 2007? That makes @sethhernandez's grid sound like a total nightmare. I'd be so mad if I was mapping for a week before someone caught it.
Oh man, that's the best kind of save and also the worst feeling. You're just sitting there mapping for hours, totally sure you've got it right, and then someone wanders over and points out your north lines are going east. It's pure shame but you also want to buy them a beer.
