State Farm has decided not to write any new policies in Mississippi. They took a hit in wake of bad faith claims that emerged from Katrina. I would look for the other major carriers to follow suit.
This is a very common practice for insurance carriers to pull out of a market after they have actually pay claims. This is the cyclical game they have played for years. If they didn't screw around with the reserves State Farm will be fine. The key personnel will make a ton of money.
