Been watching F1 since '86. Been to Detroit GP 2x, Montreal GP 2x. In '92, when Mansell tried to pass Senna at the first corner chicane leading onto the start/finish line, they touched, Mansell spun and was out. After the race I found a huge piece of broken front-end diffuser from Mansell's car, with a Labatts logo on it. No, I didn't go look for Mansell to sign it, he probably would have smacked me with it.
Something funny I remember at that Montreal race was at the start when the cars were sitting on the grid with the flag-girls next to the cars, a young MS drives slowly up through the middle of the grid, revving his Benetton engine LOUD the whole way up (he was somewhere at the front of the grid of course), visibly scaring the shit out of every sign-girl and other people standing around the cars.
