I suspect you'd be fine if you left to a competitor unless you managed to steal a bunch of your current accounts. Then they might get persnickity. Even then, if they are trying to cut costs, and they don't have much business out west anyway, they may be less likely to spend much money trying to enforce that agreement. You say that you're the only guy they've got out there anyway.

And I have no special legal knowledge, there's absolutely nothing to back up what I've said.
