Rich: I think the URL supplied in Post #1 got butchered some how. Try going to
https://nationalcarts.com/event/mont...up-rally-2019/
Note the MOC software changes the URL you see on the screen from the correct URL. The direct link is
https://nationalcarts.com/event/montana-owners-group-rally-2019/
But the MOC shortened name works for me in testing this response.
