I've driven like 20 to 30 miles with no top, but never that far. Man, that's just insane. We do occasionally get people that come to the club rides (in Maine) that drive their jeep topless from Vermont, and at this time of year. Not me, I like to think I know better, although when I was younger I was foolish, rode my motorcyle to high school every day it wasn't snowing. I left one morning at about -10 F and decided to see how cold I could get. I was wearing the classic leather jacket, scarf (I know, a wimp), and a full face motorcross helmet, so there was only the screen in front of my face, and my glasses. I did 95 all the way there, which was the bike's top speed (GT 750-built for torque, not speed).
Using the wind chill formula (I love math, how many people have ever seen this!) WC = 0.0817(3.71(V^0.5) + 5.81 -0.25V)(T - 91.4) + 91.4, where V is the wind speed, WC is the wind chill temperature, and T is the ambient temperature.
So I managed to get down to about -60 degrees below zero, kinda depressing, I was hoping for triple digits. The anti-freeze in the bike did gel up on me though, and started smoking heavily, I limped it to school and shut it down, luckily it sustained no damage. The temperature gauge was pinned on "H". My glasses were frozen to my face, couldn't get them off for about 10 minutes, and of course they fogged over when I entered the building. Kinda felt stupid sitting there with the helmet on, unable to see. Aaah, the good old glory days, I'm glad I know better now.
