Ice hockey fan from the UK, I looked at a globe and picked my 'local' NHL side - the Boston Bruins. A mere 3,000 miles from TD Gardens to my house. Nevertheless, I couldn't have picked a side more naturally suited to my tastes in a team. Been an avid fan ever since.
Other than hockey, I follow rugby more than football (soccer) because footballers tend to be a bunch of overpaid nancy-boys who cry like a girl every time a blade of grass catches their shin. All the same, I support Spurs as someone born in North London.
