Zig-zagging down the street. Turning in the width of the street. At speed, no less. Finishing the turn within the width of the street. Room to spare.
Dynamic stability requires friction.
At the edge of the trees, I lost that friction in the pine duff, and skidded to a stop. My heel and calf got banged up. It's sobering and scary, even at slow speeds on a side street, to come a-cropper. It's time to tighten up for the fall. Fall is coming, frivolity must give way to some more seriousness.
