evidence: Tripsite Traveler - Lake Constance [...] Jerry suggested this cycle tour several years ago. My reaction, "not me." On previous bike trips I was at the back of the pack. Once I reached the top of a hill, the group was on their way. "Get an ebike," Elaine suggested. Lake Constance has history, grand scenery and is new territory. Water is my element. If cycling proves too hard I can take a bus! [...] Lake Constance, Bodensee in German, is filled by melting snow from the mountains. The water level changes as much a 3 meters (10 feet). The surrounding plein spreads for miles. That makes cycling a breeze. But early settlers could not build on land and be protected from floods and be near trading routes that cross the lake. So they built these stilt villages. Global warming may bring this concept back!
