Heading South on US 1 near Waldoboro Maine I was distracted for a second giving a wave to fellow bikers coming in the opposite direction. We were doing the speed limit of 55 and when I looked back I noticed that the cars in front of me were stopped. Gave it a very quick stop, and the pickup truck behind me ended up beside me in the break down lane to avoid going up my backside. My wife said there was a construction sign saying Flagman Ahead that I guess I missed while waving. The Red Pickup truck behind me missed it also. We were watching the local news when we heard that about 5 minutes after we went through there a biker was killed at that spot. We always hate to hear of a fellow biker that has died but this hit especially close to home and made me wonder if a little better signage by DOT would have saved his life . Another reminder that any small distraction can kill you out there.
