Had a job to look at in Skipton and decided to ride there, stopped after 10 miles for a bite to eat in Silsden, nice temperature, no chance of rain, so far so good. Went to chain my bike to some railings..........the railings were on an incline.........so holding the bike from rolling with one hand......I reached around the frame tube and unzipped my frame bag and reached inside for my lock keys.......bit awkward as the the opening was on my "blind side". Rooting around I felt my lock keys and pulled them out.........I was suprised to see that they weren't my bike lock keys but my garage/motorbike/scooter/works unit keys. "Bummer" I thought........then they slipped out of my fingers.......and landed on my right shoe. That instant was the first time that I noticed the drain The one that my foot was over, with 2 keys on my shoe and 2 keys dangling precariously over the drain, I couldn't reach them with my right hand and my left hand was holding my bike from rolling away. I decide to slowly remove my foot from over the drain.........PLOP!
