Although I am not a fan of fireworks because of how they affect the dogs I appreciate the way Portland puts on a show. People line the waterfront and they launch the pyrotechnics from a barge in the middle of the river. Clear nights are all well and good but a cloudy even is so much more dramatic and is more impressive that some pretty lights in the sky that leave clouds of noxious smoke behind.
