All I did for prep was pick up water guns, a bubble kit and water balloons at wal-mart. I used a couple of hours in our morning to fill water balloons while the kids were at school. Did you know they have the kind that seal themselves?? Am I in the dark ages because I just found out about these. No more knots! Unless of course the little stopper malfunctions, then you have to tie the not, but STILL. They're great!. The younger kids especially loved helping fill the balloons!
It seems like months ago... but I guess it's just been one month, right??:-)
