Rode to work early one day, aaaand hadn't noticed that shoelace had wrapped around gearshift. Rolled into parking spot, went to put left foot down, and down we both went. Since it was wrapped around shifter peg, and bike was laying on top of me, couldn't reach down to undo it. So I just layed there in my parking place, bike on top of me for about 10 minutes, heard a car oll up behind me and a voice, "Need some help?" Yep, Columbus police cruiser. He got out, lifted the bike up so I could unleash myself from shifter. Yeah, quadruple knotted shoes from that day forward, no lace loops to catch on shifter.
