Senh: A city wide search, father/son disputing each other's stories, dysfunctional families ... sounds like it could be a Wes Anderson or Coen brother movie.
Senh: Apparently, the regulations on these inflatable amusement rides (which includes bounce houses) are shoddy. These devices need to be setup and pinned down correctly. Beware of windy days because wind can blow them away into traffic or even to the roof of a house. Also, they can collapse under too much weight. In general, just make sure the operators set them up for you before they leave, and kids are supervised.
