I realize this goes without saying but if you get cold easily, you will be really cold. I'm always freezing at hockey rinks. I recommend wearing lots of layers and you'll be fine. I believe I read you are seeing the Stars vs Capitals. As others have said, you are going to see 2 great teams. Holtby, the goalie for the Capitals is a beast and waters himself a lot. You'll know what I mean just watch him. Many are predicting the Capitals to reach the Stanley Cup finals and anything can happen but they are really good. If you aren't familiar with the sport you will be after this and you will be hooked. The Stars started really well but have had some issues lately but they are a good team. As someone mentioned, keep an eye on Benn and Seguin for Dallas. Have fun!
