VV - Protect your knees! Below 60 degree or so you should start to cover them up with knee warmers then leg warmers as it gets colder. Tomorrow, leg warmers would definitely be in order. You don't want to get tendonitis. You might also have a need for the warmers on the May ride.
BTW, we're having snow flurries right now up here. But we're chill'in having a beer (breaking training) and grill'in beer can chik'in. Salut!
