Loading and unloading Motorcycles-The easy way

To add to my original post-No inexperience here. OK, I was at a campground in Corning Ca. when I heard a loud crunching noise and a lot of cussing! Looked over at my neighbor and he was trying to unload his motorcycle when it went over. My post was not for me, but for the guy I met and have stayed in contact. I have plenty of experience. Been riding since 1968. Never dumped my bike. Just thought of posting to help others.
