There has been a discussion going on for several days on the LD rider list about Geico Insurence Company.
Basicly, what it boils down to is that if you ride your bike over 500 miles in one day and then have an accident, they can deny your claim.
It also seems that in some states there is a possibility that if you use a radar detector on your bike, you are also eligible for cancelation/denial of claims.
Check your policies!
The word is that Progressive and Dairyland don't have any of these exclusions.
