Explored a bit of Prague's parks this morning. Was trying to find the easiest route to Petřín - there isn't one. Long climb to get to the park entrance. Most of the paths are still icy or covered with hard packed snow. Pedestrian paved path was good. Didn't go far enough - thought the wall I saw was the end... I was way off. There was easily another mile left in that park before reaching its perimeter. Next time.
