Okay, let me get this straight. You took half mile path through the woods, in the dark? What kind of lights are you using? I'm not criticizing, I've been known to do dumb things like that myself. But... well, yeah. Hope you feel better!
I have two lights. 1000 lumens on the helmet and 300 on the bars.
It wasent stupid at all (and I take no offence by your comment). The stupid thing was 1) going to fast around a blind corner and 2) paying too much attention to the twigs on the ground prior to the down tree.
It was a painful mistake but I learned a lot.
