We were recently at a Big 4 Camping site where all sites have a bouncing pillow. We were camped near the bouncing pillow and at least 3 to 4 children a day ended up crying from being hurt - generally from the larger kids doing somersaults which sends the little ones flying. It happened to our friend's little one who has ended up with a fractured leg and the leg in a cast for 4-6 weeks. Whilst at the hospital there was another parent who was staying at the same camp site and their child was also injured. There is a sign up with all the usual warnings about the bouncing pillow - parent's responsibility, all kids under 12 to be supervised, no somersaults permitted etc etc. During our stay one of the camping site's rangers came and spoke to the bigger kids about the rules. What is the park's obligation with something like this re providing a safe environment?
