I used to have USAA (Still do for Home/Auto), but they stopped issuing new policies for bikes a few years ago - and referred me to their "preferred provider" - Progressive. Must be getting a heck of a kickback, because Progressive was WAY out of line. Tried to go to State Farm, but they wouldn't talk to me unless I also insured home and auto's (and USAA is way cheaper on those), so right now I am with GEICO.
I don't know if the State Farm thing about having to have home/auto also was in TN only - I'd like to know if there are any members out there insuring in TN that have motorcycle with them ONLY....
