I could not figure out how to just reply to the comment made by Anne whom I beleive her website is smalltownmom. She has a great site. Usually you do have to hold on with both hands but as a rider you can sometimes let go. We were going really slow up this really curvy road and so I was able to take some pictures of the motorcycle in front of us. I wsh that I had been able to video this. The road was up hill and curvy and if we had dropped the bike then we would not have  gotten back up till we rolled down hill. Even tho we were going really slow.I will post more picture of this road.
