Well, I was camping up at Mont-Tremblant, Quebec this past weekend.
Was driving past the main parking lot for the Village when I spotted a circle of Airstreams - even one that looked like an Airstream truck camper (homemade?).
Did a bit of investigating and discovered that a small Quebec circus named Akya travels around giving shows (think of a small Cirque du Soleil). They (presumably) live in these Airstream trailers that they park in a circle around their main tent. This is their website
It was certainly very eye-catching - my friend had seen them first and asked if there was a rally going on before we figured out what was going on.
Neat to see!
