I have ridden in that kind of weather with friends, here in eastern Iowa. But, we were riding bikes that could generate enough electricity to make our Gerbing jackets and pants warm. I rode a VFR and friends were riding Kawi sportbikes. I am sure my old Hondas would work in the cold temps, but not me.(battery would be dead before I got a mile from home on these old bikes)
Looks like it was a great ride.
