high school sports in canada sucked for the most part.
played hockey, ran track and cross country... and the track / cross country teams were by far the best. no one really gave a shit about hockey, we'd have like 5 people watching our games (though i hear in the states, especially places like MN and IL, they go nuts about high school puck). Track and cross country were super chill, miss a full day of class once a week to go sit around for hours and shoot the shit, chat up girls you'd normally never see from who knows where, then run for 7km tops.
I found they are also great for staying in shape, obviously won't build muscle or whatever but your fitness will definitely improve.
mostly though, just do the sports you want to do, as long as they're track and cross country.
THIS would be unreal to be a part of in high school, I have to say...
