On Saturday I bought gas at a station with a pump island similar to the one depicted above. Note the concrete end cap at ground level the end of the island. It sticks out slightly into the lane.
As I was pulling away from the pump with my right foot still at ground level, it contacted the end cap. My foot was slid inward slightly, bringing my ankle to just ahead of the peg. There was enough force from my ankle against the peg to almost make me tip. A little more force and it may have snapped my ankle. The peg did not articulate up and back as with a road scrape in a steep turn.
Fortunately my speed was just a crawl and I was able to rapidly lift my leg to get my foot out of the way (kind of an awkward move). This immediately caused a cramp in my hip flexor that only could be relieved by stopping behind the station to stretch and massage it out. Oh the joys of the older rider!
Reminder to self: look not only ahead and behind when going into motion, but also down and around. You never know when there will be a "snake in the grass" just looking for an opportunity to ruin your day.
