I'm trying to do a little planning for Skate America and I was wondering what the temperature is usually like inside the arena for skating events. I've frozen in some arenas (no matter the temperature outside) and not in others. I'm prepared to "layer," but the question is, layer in short sleeves and a light jacket or long sleeves and something heavier? What would work best for both the temperature inside the arena and outside in October? I'd rather not pack any more than I have to. Has anyone been to the Improv near the mall? How is the food?
