I was watching the Backyardigans with the girls today and wondered, do people outside of circuses walk on tightropes anymore? I’m talking about real tightropes, not metaphorical ones. Maybe it wasn’t as often as it seemed, but when I was little, back in the mid-70s, it seemed like some joker was walking across Niagara Falls or between the TwinTowers on a tight rope every other week.
