Zvuky Prahy / Sounds of Prague

On Green Thursday I planned to walk around the Šeberák lake, but on the way my attention was caught by the intersection of V Jelenech Street with the D1 highway between Chodov and Roztyly. Someone slept there under the bridge over the highway, even though there are artificial dunes in sight - a natural sound barrier, built to allow citisen to sleep undisturbed in the nearby housing estates. What can this unknown sleeper dream about in such calming soundscape? Perhaps such highway ambient could be broadcasted on a radio for car drivers as a lullaby.
