This is the time of the year in which we have to think about another safety factor, the sun. We have all experienced driving in our own cars, driving along and then turning to go east in the morning, our turning to go west at night. You can't flip that sun visor down quick enough, right?? This can be a dangerous thing especially if you are riding into that bright light on a road with no our very little shoulder. I personally have witnessed this twice since riding with a group. Luckely no one was seriously hurt. So take in consideration that the driver of any kind of vehicle can be blinded by the sun and not be able to see you.
