Thats a good point actually, being UK based, i tend to forget States in the US is how you're likely to do location redirects (that and i read Colorado as Canada... my bad).
The short answer i think is not directly. You could use the users IP address and something called mode_geoip in order to handle the redirects, it takes a bit more configuration and setup though.
Im seeing lots about redirecting on country, not all that much on redirecting on state, but a good starting point is perhaps this Stackoverflow thread. It's probably something you'll need to ask a developer to do.

Did you make a decision in the end?
