[MENTION=339610]Darth Lefty[/MENTION]. That is an appropriate title.
I went down once due to black ice, it was a late November morning many years ago. I knew I had the risk of black ice on this 90° corner, so I took it slow and cautious and made it through. Then as I went straight I thought okay I'm in the clear, only to have that thought disrupted by sliding along the road.
This reminded me when there is a risk of black ice never get complacent in your thoughts. Lucky for me there was no lasting damage to me or the bike.
I got studded tires this year and put them on any time the temperature was near freezing. I didn't want to take the risk.
