I was there on a long weekend away with the misses a couple of years back. We were on the bridge that had lots and lots of padlocks on it, just gazing up the canal watching the world go by. Along comes this bloke on his bike, cursing away in his own language and gets off the bike. He kicks the wheel and tyre and curses some more, then chucks the bike in the canal, as it had a flat tyre. Off he wandered and went out of sight. He probably found another bike soon enough, I reckon?
