Its sad what the world has come to. Years ago you could leave all your stuff with your bike for the day at a rally, and it would be there when you got back. Now if its not locked up it will be gone... About 12 years ago, on another group, I met a couple that lived out by Rapid city. We met up with some from the group at their house during the Sturgis rally... Nobody really knew anyone, yet nothing was missing in the morning after the party. The next year we were going out to the Buffalo Roundup in Custer park, when they found out we were coming out they asked if we would pick up a stock trailer on the way out. We took it out for the price of gas and they took us out to supper...
It saved them a round trip and a overnight stay on the way... That's how old school bikers do things... Not how the riders do now....
To bad you ran into someone that has no respect for themselves and their word....
