Chattanooga is doing some amazing things. I grew up an hour and half north in Knoxville, traveling to Chattanooga nearly every weekend to Rock Climb. Its easily one of the best climbing cities in the country & IMO destroys boulder in quantity and quality of routes/rock. I moved here from California to start a company about 2 years ago and have been very lucky to work with and meet so many great people. Between the amazing people, great companies moving/starting here, and the immense outdoor opportunities only minutes from downtown - it's ripe for any tech/outdoor people.
