I find it odd that they would shut down a meeting, even if those that are there ride a motorcycle.
Actual events like racing etc I can maybe see where that can be an issue, not only with bikes but cars/trucks as well. I read the article and it doesn't seem to apply to a Hubb event, but I could be wrong.
I'm sure somebody in Ontario will check it out.
