Bridge Burner St-Jean
Kickass St-Jean Baptiste party by the tracks, under the overpass just off St-Laurent in Mile End.
Basically, a minivan powering a PA system and a DJ rig, a Facebook event... and easily 1500 people with beers in their backpacks. Awesome.
nota bene: the amount of people taking pics and videos with cameraphones and point&clicks was surprising (for here).
