It was London, actually. And this tournament in particular:
Well, more than just the tournament, it was the community and the people and the films and the city all combined into one that led me to love bicycle polo. The Bike Polo Tournament at the London Bicycle Film Festival in September 2009 was the beginning of my addiction to bicycle polo because the community was so strong and the people were kind. Plus the polo was amazing. People slaying and people playing some of their first games for hours and hours and hours at the Downham courts. The day before the tournament, we played all day. The day after, too.
Go London. Keep up the good work. I'll see you at the Worlds.
