Steelers and Packers are 1 and 1a in any order for traveling fans. Better than Cowboys.I'd say so, those fans travel in good and bad times. Pats fans are top ten but don't challenge those 2, probably more due to wasting our favors to family to travel to big games during the first like 10 years of the dynasty(!)
Giants and the bay area teams (49ers and Raiders) fans can be big travelers but only on a fairweather basis it seems.
