i have a question... i'm pratically 100% sure (and it is very good) that in Usa in the Nfl there are not incidents between fans of opposite teams. am i correct like i presume ? i find it extremely good. i had the fortune to see this year 2 Nfl games and 1 Nhl game and all was beautiful, perfect, the nice clima for families too. infortunately in Europe (in the soccer) the athmosfera is different... in some games (matches) you really risk a lot... there are some games that you know they are under risk do you confirm it that is normally quite or sporadically something happened in these years or in the past ? there are some stadiums where there should be some risks ?
