It's a beautiful, sunny, clear, dry day here in SC. So why am I inside on the computer and not out riding? Because it's friggin' 40 degrees outside!

I haven't ridden in 2 weeks. Forget about getting me out in the morning on the way to work-the birdbath has been frozen over every morning. No matter how many layers I wear, I get around the block and go "NUH UH!" and revert to the cage. It's not the discomfort, really-it's that I can't stop shivering. If I can't stop shivering, I can't steer.
It's so cold, I can't steady my hands long enough to check tire pressure.
Maybe it's that I feel the need to wear a t-shirt, knit shirt, and a sweater indoors (at 68 degrees). Maybe it's that it was 90 degrees here 2 weeks ago, and the temps dropped overnight. Maybe it's that I rode all summer in the same 90-100 degree temps, with 80% humidity.
All I know is, if I can't find a jacket with the equivalent warmth of my ski jacket soon, I will be wearing said ski jacket (which is not bike-friendly-it rides up in the back) until the temps come back up to normal. And if I don't ride soon, I'm liable to go postal.

I've tried leather and textile, and nothing seems to cut the chill. I don't think my bike's battery will handle heated gear. So if you folks in the colder climes would be so kind as to: a) tell me what you wear or b) take your cold air back, it might prevent me from moving to, say, Costa Rica in search of tolerable temps.
Thanks for letting me rant!
