During a recent tour of the Garden we were told, there is an ice ring for hockey, when hockey season is over they put a retractable wooden floor over the ring for basketball. They discovered that during the dog show the dogs won't walk on the floor unless the ice is melted. Why won't the dogs walk on the floor? That is the million dollar question for today.
You have to be careful of those tour guides! A few years ago in DC we were on a tour of the Capitol and the intern leading the tour told us that George Washington died in battle. When we told him he was wrong he said "Are you sure?" He was skeptical when we told him Washington died in his own bed at Mount Vernon!
If you believe the fine people in New York keep the ice rinK up all year, I have a bridge to sell you which is not too far from the Garden.
First, that message didn't say the ice is on all year. The message said that after hockey season, a retractable basketball court covers the ice. Ice hockey and basketball seasons overlap. So yes, sometimes the b'ball court does cover the ice.
Moreover, the ice is not used only for hockey. There are lots of ice shows at the Garden through the year.
