Why are you saying pipe down. Thousands of kids will be having a great time playing at shamrock. If its too cold for you and your son, stay home. When all the kids go to school monday, laughing and talking about how they had a great time playing lax, that weekend, your son can say he sat at his kitchen table , nice and warm. There really not much more to say on the topic. When you bought your house on long island, I'm assuming you were aware of ny weather. Dress warm, or don't play. Whatever you decide, nobody cares.
