Our group had 4 cancellations for the Canadian Grand Prix this year, June 23, 24 and 25 in Montreal. We have, I think, the best seats at the track, Stand 12 at the Senna corner. It's the 1st corner and the pit out exit. The beginnin gof the race is amazing, and Senna is one of only two or three overtaking points on the track.
It's taken us years to get these seats.
In case anybody is interested, the 4 tickets are on ebay, in pairs. Here's the link. Follow "seller's other auctions" to see the second pair.
If you are interested and have any questions, I'd be happy to answer them -- my buddy's secretary put them on, since neither of us knows anything about ebay.
