The owners are investing in this resort, and it is one of the best near Toronto, but the parking lot is awful and needs a lot of work. Cannot be that much to put asphalt. The potholes are enormous, and are getting worse every year. Not only cars get damaged, but a whole horse could get lost in them. C'mon guys, if you love us take some action. I shudder every time I see the entrance to the parking lot. In days with crowds you have to drive around quite a bit through the potholes to find a spot to park.
