What’s a bonspiel? No, not a beer garden song contest. It’s a curling tournament. What is curling? It’s that Olympic sport where players sweep a stone across ice. All day on May 27-28 you can see what the excitement is about at the 5th Annual Golden Gate Bonspiel at Sparks Ice in Fremont. 36 teams start competing around 6 in the morning and continue all day. Free.
