I lived in Calgary for 4 years before we had smart phones w/ maps. The grid system was amazing, it was like being able to give easily processed human GPS coordinates. "Let's meet at 7th Ave and 9th Street." Done!

I gotta admit I used to think I just had a great sense of direction.

Then I moved back to Europe and realized it was a lie. It was just that the grid systems of the places I lived in the US were much easier to navigate.
