Your kid will remember this birthday party forever. Money can't buy memories like that.
I am sure Andrew will remember this, even though he was only 4 1/2 at the time...
When I turned 10, my dad turned the entire yard into one giant water-park. 2 kiddie pools, sprinklers, slip-n-slide, crazy clown, water balloons, squirt guns. Pizza, cake, candy, all sorts of food. All the kids in the neighborhood came.
I leave work early today. I'll stop by a few places and look for those balloons for ya. If I find some, I'll overnight them to you.
