They have backed off a bit on that. It seems they would just like some appreciation for using their parking area. They now have a donation jar inside the restaurant where you can drop your appreciation donation. Last I read on it.
I was in Mount Forest yesterday and that parking lot was full. Also, people are parking at the Canadian Tire, A&W, and the Canabis store in between. I also read that you can park at the arena and follow the path over to the trail. I have no personal experience with any of this.
That is not exactly what the notice from the MFD stated. Besides the fact that you are responding to Tricky who was involved in the discussion from the get go and thus knows all about it.
