F1 week in Montreal is the wilder of the 2 events clearly with more testosterone flowing ... more groups of guys turning it into a "guy's week" or a "guy's roadtrip"... i doubt it's going to be any smaller this year due to student activities. visitors don't care... it's just students protesting, marching the streets ... it hasn't been a Stanley Cup parade with rioting thus far and it's gone on for a while now in a fairly civil manner, good for the students not swaying from their position to bring some BS to light.
I agree with MrLube, a reduction in service quality during weeks featuring a major event historically with SP's keepin' their eye on the cash flowing into town and booking themselves for extra shifts or extended hours. but then again, visitors never feel that drop in quality (only the locals + regulars sense it) because let's face it Hobbyland's GFE service, even at 50% capacity is still better than just about anywhere else at 100%.
