A lesson learned tonight. Don't be lazy and leave your slicks on if there's a remote chance you might hit ice. I did just that tonight on an exploratory ride on the local tracks to see if they were clear of ice. The answer was NO! Only about 10 yards or so mind you but enough to turn me upside down and into a fence with an almighty thump. Thank goodness for helmets. I'm too embarrassed to actually admit to anyone back home what happened but I've learned from it..........(I hope).
