C., I just want to add my support to what you're saying and would also be interested in knowing if there are some more interesting playgrounds. If I had the money to invest I would most definitely open one up. Not only would it provide a valuable service to the community but it would make a fortune!
I am a 40 year old mother of an almost 4 year old boy, almost 2 year old boy and another baby due in December. I'm Australian but have been living in the States for just over 3 1/2 years
