The shop that the brothers owned when they flew was actually taken down, along with their home, and rebuilt up in Dearborn Michigan at Ford’s Greenfield Village. You can walk through them and see it how it was during that period of use. If this building had any value, I am sure old Henry would have scooped it up as well.
Sounds like Dayton missed its opportunity years ago; at least the Wright Bros. got the back of the Ohio quarter.
