Here are the GPS cues for the few early-birds that want to add on some miles prior to the 9:30am long ride. This adds 13.5 miles, so we'll end up with 52 sub-freezing miles for the day. This 8:30am (sharp) "warm-up" ride will only go if the main ride is going, so watch the bb in the morning.
Tomorrow's a good day to pull out those insulated water bottles that you use in the summer -- they'll help keep your water bottle from freezing. Maybe a teaspoon of gin or vodka would help too. :)
