The Proclaimers is my "worst" Ear Worm but there are others - Rick Astley's, Never Gonna Give You Up is another but I don't mind it really.Womack and Womack’s Teardrops is like that for me - I need to quickly turn off the radio if it comes on and even then can’t get it out of my head all day
Did the "Canal du Nivernais" 2 years ago on a rental boat for a long weekend. Friend of mine knows how to handle it (well). I remember white wine (Bourgogne) and narrow passages... The dams and locks are an awesome experience on their own. You need to know your stuff!
Probably a once in a lifetime experience for me. I wouldn't trust myself being responsible navigating a boat through those narrow canals. Although great weekend/memories, I feel more comfortable on my bike!
