First: It was a couple of 8 year old boys causing a ruckus on the streets with some noisemakers at around noon.
Second: It was a high school band marching down the street in the around 2pm. Strange? But not really, since its the Olympic season.
Third: On my way home from wandering after Olympic people watching, I hear the same drums I heard earlier. Theres a huge crowd around them, are they buskers? Loud and quite talented buskers in the middle of Robson and Granville? No, they're the DDT Drumline, a high school band from Vancouver Island, there's about 12 of these kids. (probably the most interesting street performers I've seen yet, and I've seen Batman doing tricks from his used suitcase). Their infectious drumming made the crowd wanting more, but like seasoned professionals they kept on marching along. Down Robson street where the crowd got bigger and music got louder. Where were they marching to? Back home to Duncan, BC, I assume.
