Grain Trader you sound like me.
i understand there is a lot more than just the car race as I noted above our son goes every year with the Ingersoll Pipe band and don't think he is going just for the cars going in circles.

I got this from him about preparing for a parade today

And this video taken by someone in the parade from the looks of it.
The Gordon Pipers-Horse Shoe Pipes and Drums marching with the Ingersoll pipe band too

Sometimes the BIG tourist things are to close to home to bother with.
Not far from the Stratford Shakespeare Festival here and although I have been it is not something I would go to again although some people come from a long way regularly to take it in.
