Umm right beside Doha College school theres the rugby club. If you ask the School security theyll direct you to it easily. However they dont play American football, they play rugby ! Umm i dont know whats the diffrence except in the gear that is worn. But hey give it a try, u might find it enjoying as well ! And on some nights theres good games there and theres a bar and lots of people who are fans of the game. Cheers !
