Mary Kay, My neighbor has a bounce house business. He has over 15 assorted bounce houses and slides. Here in the Dallas/Ft. Worth area the winds have been crazy for the last several months. He called a client just the other day and told the father of the child who's birthday they were celebrating with a slide AND bounce house that he had to cancel due to high winds. The father lost his mind and was screaming and cursing at Scott. According to safety regulations those bounce houses and other inflated "toys" are not to be used in wind over 20mph. That day the winds were over 40mph!!! What's more is Scott stakes them down with a two foot stake and a 50lb bag of sand on each one of the stakes. This video according to Scott, the owner of the bounce house didn't even stake them down that day!!! It's amazing that the kids weren't hurt any more than they were!
