The NY legacy teams always have a strong fan base on the road. Transplants, fan clubs, and vacation road trips usually insure their presence is heard.
I used to be a member of the NY Rangers fan club, and their road trips were things of legend. In the early-mid 90s, the NY Rangers had their home ice at Madison Square Garden, and the majority of the crowd for away games at NJ Devils, NY Islanders, Hartford Whalers, Florida Panthers, and TB Lightning.
