Now it's normal for me to spot people by recognising their bike first. Or sometimes (as is the case with Kirst's panniers - though she often blanks me in a steely stare of concentration) byy various accessories on the bike.
This morning I spotted, and reconised, Min by her riding style as she silhouettedly entered the top of the Innocent Tunnel while I was halfway up.
I think, maybe, I need to get a life...
