Is there any escape from noise?


APRIL 5, 2010 – Gosh, Darned Summer in the City.
By Matt Weingarden


With the coming of summer in the downtown core, out come the noise police.
My apartment building is full of these whiny curmudgeons. They want to rain on everyone’s parade.
Seems everyone who buys a decibel meter is an expert Acoustician.
Those folks run around the building complaining of gigantic decibel levels. It’s amazing how they quote numbers like they actually understand the science of sound. The noise police band together to better the downtown core, to raise awareness and complain for the greater goodness.
They actually had the gall to try to prevent several new nightclubs from getting a liquor license last year.
Some folks have no life and need to live in chaos.
We need to work together to make our downtown vibrant. We need to bring families back to the core. The Downtown Windsor Business Improvement Association is doing a solid job. They are learning from last year’s mistakes and working to make this year’s events even better.
There were so many great events held downtown last summer. So why can’t we all get along?
My condo overlooks Pelissier Street. The answer is easy for me. I simply shut my windows and turn on my air conditioner for a couple hours. It works.
And I mind my own business.
