I was out getting a bit of exercise for my knee and came across some canal work. Actually, I think they were fixing the side of building but it was so close to the canal that they had to drain it in order to complete the work. I am still fascinated at this ecosystem they call Venice.
From the pictures, hopefully you can see how much water was drained out and really how shallow the canals are in general. I dont think anyone could drown in them but rather they would probably die from the putrid mess they are sloshing around in!
