I think it is totally awesome that kids have no knowledge of all the *crud* that we adults have to deal with.
We pay a membership fee each month for our gym with a pool like this:
My kids are completely content with a 20 dollar blow up pool filled with water, dirt, grass, and who knows what else, thanks to my 2 year old.
Don't you wish that we still were able to find the fun in EVERYTHING and that we didn't need big expensive toys like televisions and movies and computers to make us happy? It is just one of the many reasons that my kids are the joy of my life!
