So, guest list made and invitations sent, we eventually came up with several "adventuresome" games: an obstacle course, "Sinking Rocks" (a cross between musical chairs and a cakewalk-type game), "Storm" tag (like freeze tag except you "sink"), and "Don't wake the Guard Dog" (which is like Red-Light Green-Light --- trying to sneak up on someone without getting caught moving). Unfortunately the weather was nasty so we had to build an indoor obstacle course, which I (of course) neglected to take a picture of... We also swapped the tag game for a signal flag matching game (with international nautical flags copied off the internet).
Instead of individual prizes, the kids earned pieces of our "Treasure Map", and when they put it together and figured it out, it led to a group reward: little treasure chests Mike had helped me paint, filled with glass "jewels" and very shiny pennies. There were also candy bags for each of the kids, too. (The map was a simplified diagram of our house that Matt drew for me and the big treasure box was in the oven.)
Fortunately that killed enough time to move on to presents and then cake & ice cream. Matt had been entertaining Esther (and keeping her from getting trampled) for most of the party, but he joined us in time to offer to help cut the cake --- with his chainsaw!
I think the kids had fun --- they certainly were Loud Enough! Sheesh! I guess I should have expected as much... So, here is a little collage of the whole shebang....
And this (just for fun) is the really cool e-card I wish we'd found in time to send for an invite:
