I can contribute a little to. Great thread, fun to read.
This last summer I was taking one of rides around Mt Rainier and stopped to take a picture (all ready have lots) when I was approached by another bike rider also stopped. He had lots of questions about the rig and stated he had always wanted a ride in a sidecar. He asked if I was coming back this way? I indicated I was doing the loop around & through the park. He wanted a ride, so I dumped the water out of my two plastic water containers I use for ballast, he secured his bike and off we went. We went through Mt Rainier park, out the other side, back up HWY 12 to the the other park entrance and eventually back to his bike which was still thee on the side of the road. I think it was a little longer ride than he planned on, but he didn't complain.
Only two defining forces have ever offered to die for you: Jesus Christ and the American Soldier.
One died for your soul, the other for your freedom.
Focus your eyes to where you want to be,
Not to where you are afraid of falling to....
