I hate to burst your bubble, but outside of the major metros, there are few data science type jobs that are any good. It's an up-and-coming field, maybe--but as someone with a PhD and a lot of software development experience, making the transition has been tricky (am still working on it). It may be a good track or it may fizzle out, we'll see.

A few superstars will do well, the rest will be an urban myth of potential prosperity and happiness.
