a tent awning in Tower Grove Park between playgrounds. Sprinkler fountains should still be on, bring your suits.
Bring lawn chairs, Sun block, bug spray, kids swim suits and towels and yours too if you want to get in the sprinklers with the kids. hehe
I will be making Cup Cake Ice Cream Cones if I can figure out how to get them there without melting them. http://thefrugalgirls.com/2010/02/ice-cream-cone-cupcake-recipe-so-cute.html
No theme... just party time at the playground / park.
