Well, for two main reasons. Transportation and money. I don't have any Money now to go to shows, or for taking the bus/Metro. Which means that transportation is a problem too, I'm just 16 so, I can't drive, and I can't ride bikes (sadly). Oh and also, school is a problem too. Since I don't live in Montreal, it takes time to go to a show and come back and I can't afford taking a day off from school.
The shows I listed on my last post (except the Lights show) are all near the Montmorency College, which is not realy that far from where I live, in Laval. And they are in average 14$ each.
So, all I can say is, Joseph, you better enjoy those damn shows. ^_^
