Went to visit some family members in western Canada in July and came upon this vacation phenomenon.
Now it isn’t an official campground nor is it authorized by Walmart, but it is a practice that seems to be on the increase. Last year at this time there were perhaps 2 or 3 RVs or trailers in the lot on any particular the night. On this day, I think it was a Tuesday, pictured below there were over a dozen scattered around the edges of the parking lot. On weekends there are considerably more.
They paved paradise and put up a parking lot. -Joni Mitchell
