Only 19 miles this morning. Temp was 18 F. I had a great ride as i debuted my super d duper Visor Gogs. I was very comfortable all the way. I had my first flat tire in these temps today. No real problem except that my cheapie frame pump did not want to attach to my valve stem very bad. I think i need to look into CO2 for these temps.
My wife and kids had a great time making fun of me when i tried these on last night. That is an added bonus. Not only do they keep your eyes from tearing in the cold, they also make you look like a complete dork, which provides hours of entertainment for your friends and family.
