+1 on all of ya.
I hit it a few times when commuting year round, usually just a quick slip, but the worst was on my first Burgman 650 on I5 under a bridge.
Probably a 10-20' stretch. I wasn't going particularly fast for the road, but I was on the freeway..
I didn't twitch & thought only pure thoughts for the duration and stayed up. Longest 5 hours of my life.
Stuck to surface streets on the freezing days thereafter. Fortunately not a lot of them around here.
A few yrs ago, on my 5:30 AM work commute - I hit a patch of ice on a street.
I didn't go down.
It came from a street cleaner a few blocks ahead. He was spraying water so his swirling brushes didn't create dust!
This happened one other time - in the 70's in Mass, work commuting to the Hosp. in the winter on my Honda motorcycle. The same cause! Didn't go down - but I was just as P O'd
Dumbheads.
