I have had some really close calls...a couple my stupidity, a couple others stupidity... Riding aggresively defensive seems to work for me quite well. But yeah, there is allways evidence (BusaChick's accident) that no matter how far ahead you plan, and how on top of it you think you are...bad things can still happen...This is what gets me putting that helmet and leather on every freakin time... Now I really want some good riding boots and pants...
We accept the risks of our hobby/passion/addiction. We know they are there, we accept it, we manage them, we ride because it makes the world right...at least every time I twist the throttle it's right... Be safe all...
