Riding With No Helmet

A few weeks ago  I took off on the trail without my helmet.  Not sure why I forgot it.  It was at the trail head, I just got wrapped up in whatever I was doing.  I realized I didn't have my helmet about 100 yards into the trail.  I figured I'd just ride careful and there would be no issues.  FYI:  You would be amazed at how many little branches your head goes through on a typical ride.  Branches you never noticed until you ride through them without a helmet.  I will not forget a helmet again.
