I am just starting to show interest in this sport. Being from England I know nothing about NFL and I never get to see it. But I was wondering I know the teams have big stadium but are the fans like in England ( soccer fans ) do the fans of the visiting team travel to watch the game and and the stadiums have a special section for away supporters with acouple thousand seats or more? If so is security tight ? Do the fans get very heated and kick off and sometimes fight?
