This was me in the woods last night.
I rode straight into a sharp branch on a fallen tree at around 15mph and got knocked clean off the bike. It hit me a glancing blow in the side of the neck (right across the jugular - yay!) and left a nice cut.
I just didn't see it in the dappled sunlight as it was pointing towards me like a spear. A few inches to the right and it would have been perpendicular into the hollow of my throat, and a few inches higher than that, right into an eye. It was fucking
stiff so I shudder to think what the outcome would have been, even with safety glasses on. I've no doubt a direct blow would have pierced my throat.
Shook me up, it did. But I remounted and rode on like a boss after exacting justice on the motherfucker.
