A plea to all drivers in vehicles. I like to bicycle for exercise during the warmer season. I can not tell you how many times I have nearly been hit by cars just this season so far. I bike on paths where sometimes I have to cross residential streets. I'll use Pioneer Trail, near Flying Cloud Airport, as an example. Just the other day, I could have been hit four times in a 5-minute span if I hadn't been paying attention. The common denominator is either drivers roll through a stop sign or fail to look both ways and just assume that no one is coming. They are always surprised to see me, or worse, they don't even care. I would like to apologize to one driver that day that bore the brunt of my frustration. She looked very young and I frightened her when I shook my fist. But the majority of drivers should know better. So please look both ways and yield to the bicyclist when they have the right away. Thank you.
