People in Ottawa used to get about as upset about Bluesfest when it was held downtown, because there was some music from a summer festival for a few nights. They're not really a good measuring stick for how disruptive something is, more like a bunch of entitled civil servants that don't want to be disturbed while they cross off the days until their pensions arrive.
Comparing truck and ship horns with closed circuits for 22 hours or more a day to "music from a summer festival" might not be the MOST disingenuous comparison I've heard, but it's pretty close, if not.
