^Can't help you very much because I don't live in Chattanooga, but if you enjoy the outdoors then you'll love it. Plenty of hiking, kayaking/ canoeing/ rafting, camping, and other outdoors activities. Its an amazingly beautiful part of the state. If you like to snow ski Cataloochee in Maggie Valley, NC isn't too far away (mainly fake snow) as well as the Great Smokey Mountains National Park.
As far as developments, downtown Chattanooga is very nice for a city its size, and Nashville and Atlanta are roughly 2 hours away.
