Pool party!

Nine kids (and a baby) plus one kiddie pool and a sprinkler = FUN!!!

Throw a swingset and sandbox into the mix and it's even better.

All afternoon the parents commented on how well the kids played together.  No arguments, no quarrels, no conflicts whatsoever.  Nothing but smiles and squeals of laughter. 

That makes for a perfect party in my book, even if it IS 95* and sweltering.
