The clipless pedals got me about 2 weeks ago when I went out for a ride. I was on the way back home from a 12 mile ride around the area, and the wind was picking up. I was at a corner and stopped for an oncoming car on the cross street. I had unclipped my left pedal, but a sudden gust of wind came from the east (I was headed south) and blew me down. Nothing like going down the direction you weren't planning on in slo-mo! Luckily, the car was well past when I went down. You know it will happen sometime!
