I received a freeze warning alert from the weather service this evening, with temperatures in the AM expected to be in the high 20s (F). The trick is by the afternoon the temperature is expected to be 35 degrees warmer -- and I can't practically carry two sets of gear -- well I could, but only in the morning. The bulkier gear from the morning could not fit in the space of of the thinner warmer weather gear that I would wear on the ride home.
Alas...
