I played street hockey in Riverside Park when I was a kid. I played goalie. I didn't make the hockey team in college, so I played lacrosse instead. I didn't play hockey again for 20 to 25 years, and then my son became interested in the game. I decided to pick it up again. A friend let me play backup on his team.
