- weather, Tennesse weather is not really that good compared to places like Boulder or California
- deep south, means you can't really be a foodie or god forbid vegetarian
and a lot of other problems, like US visa immigration. How many of those startups are willing to sponsor H1B, even if it's possible to get one?
PS. my choice of rock-climbing destination is Cape Town, South Africa, which is far off-the-way, but is definitely superior to Chattanooga for climbing.
EDIT: people point out that there is decent food in south - so maybe I was just incredibly unlucky or something.
