Shopping Malls and Marinas have something in common, both are best avoided in my opinion, but both are hugely popular. Imagine a noise free Mall? It just won't happen, even on the eleventh hour of the eleventh day of the eleventh month. Solution, avoid the places like the plague!
In the meantime, I just hope that Authority keeps up the pressure. As many of you know I have the great good fortune to live besides the water. Long been our way to sleep with the windows open during the warmer months. Great, love the natural dawn chorus, but nowadays that chorus is quite likely to be the roar of someone firing up their engine. Not nearly so loud is a boat's central heating, in the summer for heaven's sakes!
Sound travels over the water, I have both a yacht station and a twenty-four hour mooring within half a mile of my home. Depending on wind direction either or both can be a source of early morning noise. Not always loud but nevertheless unnecessary and annoying.
