Carrick's kind of between the South Side and Brentwood (at least that's the route taken by the Carrick 51C bus!). I believe Brentwood Blvd. is the main street through there.
i am getting a working knowledge of where it is now, thanks! the hockey tourney was actually over in the South Hills, so believe me, it felt bizarre to travel to my HOMETOWN and still not know where the stuff is located, bc i literally NEVER went over to that side. i got a little bit more familiar with the South Hills after the last two hockey trips. Great shopping over there! and NO SALES TAX IN PA, always a mental incentive for me to spend!
