Bats are good

Bratislava is a lovely place where to stay if you want to relax. This city is a real jewel embedded along the Danube river. I stayed there four days between the month of June and the month of July 2010. I almost found the same climate type as my city of origin in Italy, which is Bologna, so I got accustomed without major problems.
The point is that at nights the city gets overcrowded with aggressive and hungry biting mosquitoes. I figure out that this might be a peculiarity of cities crossed by a big river, which makes the air more moisty.
I'd really like to provide a suggestion to the municipality in Bratislava. Adopt bats. Bats are good, because at nights they feed themselves with big quantities of bugs, mainly mosquitoes. I'd suggest every inhabitant in Bratislava, every family there to build boxes for bats outside their houses. Then you all would see the difference.
I am not making fun of you, I am serious. I really want to cite you the example of Fiesole, a town close to the marvellous city of Florence. Fiesole sits high on a hilltop above Florence. Overlooking a lush green valley, it is untouched by modern cares. Bats glide through the sky. Blue wood smoke rises from faraway farm houses. Dogs bark in the quiet distance. The normal world in which we live vanishes into the perfect atmosphere and clean air of Fiesole. This is a place where one can sit and reflect and be at peace with the world.
