Personally, I think our traffic is much worse than Boston and a little worse than Chicago. At least in both of those cities you have the option of commuter rail and Chicago has those reversible lanes. I have driven in both cities quite a bit and very recently. As was mentioned, Atlanta is very directional. I purposely live in the opposite direction of traffic from my office. I have an 11 mile, 15-20 minute commute when the opposite lanes are a miserable parking lot. When I lived in the direction of traffic, 45 minutes was normal and an hour was easy with an accident between downtown and home.

Our public transport is not good. I am always jealous of other cities and their systems.

If you are into arts, try the Virginia Highlands area as a destination. Lots of locally owned shops and restaurants. Some nice bars and a good place to hang out at night. Maybe check out Little 5 Points as well if you are into things a little outside the norm. The Vortex is a great spot for a beer and a burger.

Also, Atlanta is not the best city for walking. It's very spread out and I speak from experience saying that you have to watch cars more than they watch you. A lot of Atlanta drivers are quite oblivious to pedestrian traffic. I walked to lunch every day for years and had to always be very wary of the people who ran the lights or stopped right on the crosswalk.

For the trendier nightlife, you will want to head to Midtown. Lots of clubs with covers and loud music.

We aren't club people at all but usually end up at the nearest Taco Mac enjoying something from the vast beer menu and just hanging out.

Housing is very affordable. You can own a home here easily.

The Aquarium is very nice and if you are here in the next month or so, they do Friday night jazz. Details are on the website. The botanical gardens are nice as well. We have a lot of parks and the Chattahoochee River has a lot of recreational areas along it and you can walk, jog, bike along the trails and a few of them have canoe rentals.

Good luck! Sorry I can't tell you too much about Henry County specifically, I've never lived there.
