I am no pro on Cobra insurance since I am still shopping for a car. But I am from NH.
I have a buddy who has an FFR in town and I will get some infor from him.
Also, you may want to check the local club section here and get some e-mail info on others that may be in the area.
Another shot is the FFR website, for owners in NH. I believe there
were some NH owners listed when I was picking their brains.
