Don"t know what you mean by "speak for yourself", but yes, I am speaking for myself on what I know about this subject.
I was born and raised on a flat-land Iowa corn and bean farm. When I moved to Wisconsin 40 yrs ago I saw one of those side hill hitches and didn"t have a clue what it was.
Now I go to shows and when people ask "What is that thing on the drawbar?" I know they are flatlanders.
