How cold is too cold?

[Brandi]

We've had temps in the teens and 20's this week and I've cycled in it. Today it's 17 F/-8 C.

For the TE'ers here, I wonder......how cold is too cold to cycle?

ARE YOU NUTS!
Ok I can't say anything in this thread I guess. I mean I rode about a week ago when it was about 45 and there was wind so it was colder then that..BUT I was frozen when I got home! I had to take a hot shower to feel my ears again. I decided it had to be at least in the low 50's from here on out. All you snow birds probably think I am a whimp. But it is what you are aclamated too right? My blood is probably thinner then you girls who live in the snowy places. It has gotten to 19 here before. But the roads where icy so I wasn't going to try that!
But I live by the ocean and it is not warm water. You have to wear a full wet suit and booties or you will die! So the wind that comes off the ocean here is so cold in the winter.
