Ok...so this morning, I looked at my temp gauge at home and it said 31 degrees. I thought, "yeah, its cold, but I'll bundle up." I put on two t-shirts, a thrmal top, a sweatshirt and then my three layer jacket along with my riding pants with sweats on underneath and two pairs of socks and two bacalavas. I started riding and about 10 minutes into it, I was feeling pretty damn cold. I was pretty miserable as I rode, but had to keep going. My fingers were pretty numb and I just felt chilled all over. As I came across the Bay Bridge, I could feel that the temp had warmed up some from where I started (home/Napa). Once I got to work, I watched the local news as I defrosted, and the weather guy said that Napa had dipped down to 25 degrees at the time I left and the current temp in the City was 41 degrees. 25 degrees was just too damn cold for me with the wind chill factor and all....my hang guards may have helped some, but not enough. My finger tips were pretty cold. So, yeah the hand guards blocked a lot of wind, but the outside air temp was just too cold for my gloves, I guess.
So, all in all, I think if its about 38 or below, I'm gonna drive into work. I was just too uncomfortable for that hour long commute. Plus, I was too worried about hitting black ice, having rained here over the weekend and all.
