The other day I was riding into work and I saw some inner-city kids walking to school. One strayed right out into the middle of the road where I was headed on my bike. He stopped and bent over as if to examine something in the middle of the street.
I prepared to avoid him by moving out into the middle of the lane while I waited to see exactly where he was going. But as he moved back towards the sidewalk, I gazed at the area of the street that seemed to have caught his interest.
It turned out to be an open manhole, right in my path.
I don't know who thinks it's cool to steal manhole covers, but I hope 1,000 fleas infest his armpits for a day or two.
(Be careful and know your route well.)
