Kiddie Pool Kickball

Doesn't this look like it would be fun to play on a hot day?

It is sort of a Slip & Slide version of baseball with kiddies pools for the bases and you use a kickball instead of a baseball.  

You would need four blow up kiddie pools (around $15 each), some Visqueen (20'x100' costs around $100), water and a kickball ($7-$12), so around $175; not super cheap - about the same price you would pay to rent a bouncy castle for a day for a party, except this looks like it is more geared to tween-adults and reusable, unless you spring a hole in one of the kiddie pools.
