I am seeing some of the wheels have treadle conversion kits to add a second... maybe that is the route to take. When we go to Ohio I am going to look for a place that I can either go for instruction or at least test out a few wheels.
Due to the weather out breaks in our route to Ohio we may have to leave later in the month than we have planned. These tornadoes are so terrible. It is all bringing back memories of the Xenia, Ohio. That storm left debris from Xenia in my back yard. It was awful.
I hope all our friends are safe.
