I had a nearly identical little "near season" ending cartwheel off that same damn bridge last year. It was a bitter cold Monday afternoon in the mid teens and I had the day off, so I decided to get a few extra hours in after a big weekend. Even thing was going fine until I hit the bridge and went shooting off of it like it was coated in grease. I didn't even have a chance to clip out or grab the brakes. I went from an upright wheels down position to being impladed on a spear shaped rock 3 feet down in nano seconds. I actually layed there for 2 or 3 minutes, not sure to cry or crawl down the hill to car. It was so cold, that the water I found after crashing through the layer of ice, froze on my gloved hands on the way out of the woods. I managed to call my wife (who is an RN), and she gave me her stock reply answer to my bike crash woes," It cant' hurt as bad as giving birth". She then proceeded to break my horns about "base miles, road riding, HR zones and everything else I figured she never paid attention to, when I spoke.
So in good natured ball breaking I gladly pass it on to you.
Happy New Year
