Fall in east is one of the most beautiful sights on earth. The leaves are on fire and the cool air reminds me that it is almost time to break out my ski boots again and see if I can remember what I am doing on snow. It is also the time of year when I start driving down to Highlands Mountain Bike Park in New Hampshire to give my downhill bike a little bit of a workout. Downhilling on the east coast is a blast, but it can be extremely uncomfortable in the summer when the humidity is through the roof and the temperature is around 95 degrees. Wearing a full-face helmet in that kind of weather is less than enjoyable. In late fall, however, body armor provides extra warmth and Downhilling becomes a far more pleasurable activity. I also came prepared with my Mammut Jungfrau T-shirt as an anti-chaffing underlayer to keep me the perfect temperature and my Pike Jacket which is quite possibly my favorite layer for warmth in the entire world.
