Nick,
The Ingersoll exit was Culloden Road and we met at the Tim Hortons at the first light north of the 401 ....right across from the CAMI Plant (GM).
Anyone coming from the East or South could meet here then we could proceed to a place in London near the show to meet up with the Western and Michigan group. Beaner has scoped out an Esso Station fairly close to the car show as a final meeting place.
