I don't think that's the problem. You didn't see the crowds for Race Weekend? Go out and see the crowds for Ride for Dad next weekend, Bluesfest, Folkfest, Ribfest etc..
Getting people out isn't the problem, they just see the Spezza thing as pointless, whether there was 20 or 20,000 people in that Spezza rally, doesn't make a lick of a difference to what actually happens to him this summer. I wasn't going to go and all the power to the people that did, but it's not because people of Ottawa don't go out..
A little off topic, but I still don't understand the logic behind the "Ride for Dad" event. If I have my facts straight: in order to raise money/awareness for prostate cancer a bunch of people are going to ride around needlessly, as in they aren't actually traveling anywhere, on motorcycles further polluting the air and destroying the atmosphere? Not sure if increasing the risks of skin and lung cancer is the best way to fight another form of cancer.
