I rode too.....couldn't believe the 62 degree weather.
I did overdress....got too hot, and didnt have the kind of clothes I could zip and unzip as needed...I will learn how to do this better.
I also got a flat.....grrrrrr. I think the CO2 cartridges are one of the best things invented. I don't have the hand strength to pump those stiff pumps.
It still takes me quite a while to get them fixed..but I did and then went on my merry way. It was a great ride, on a sunny winter morning.....felt good.
