LOL, so true. I mean, all they had to do was look on the map or read ONE guide book about Pittsburgh and they would've figured out that stuff. Upper St. Clair was out in my book due to the zoning for horses/stables but that is what I think would possibly be the only place Brian could've logically driven that was at least perhaps the same direction toward WV that would've made Justin make that comment in jest if he did, as most other 'upper class' boroughs are the opposite direction of WV.
But they weren't very good with directions, so it could still be those places.
As frustrating as some of the things were in qaf, at the same time, because of this it leaves writers with a little more room for their imagination and interpretation when making up for the inconsistencies.

I've always found it odd that they chose Pittsburgh and seemed to know so little about it. Have you been to either Pittsburgh and Toronto. I know Pittsburgh but I've wondered if Toronto reflects it closer than perhaps other cities they might have chosen for the location.
