I am currently doing my internal med rotation at mount vernon ny and I have done my peds, ob/gyn, pysch, and family in atlanta.
1. When I lived in atlanta I lived in buckhead, it was the nicest part of atlanta and it had a lot of fun things to do and see and you never had much traffic because while everyone was going in town you were going out. (must places were about a 5-25 mile drive). I highly recommend living in buckhead in atlanta. In ny I live in white plains area. I do drive and it is about a 20 minute drive each way. Its really easy and really safe. I wouldnt recommend living in mount vernon, but to each his own.
2. the preceptors were good in atlanta but there was a lot of clinic work. You worked with attendings in atlanta. In mount vernon it is pretty laid back and you have to make your rotation. If you are not a go getter, I wouldnt come here, but i find it to be alright. You work with a lot of interns and residents.
Both places that I recommeded are extremely safe and I have not once been concerned about my safety. Dont live in downtown or south atl, and try not to live in mount vernon. Go north in both instances
5. Atl public transportation - BAD
NY public transportation - GOOD
