With so many dancers at the party, of course we had a blast with music and lots of dancing (Thanks to Saydi, the DJ!!!).  We had a "dance contest" with two couples where they had to wear inner tubes while dancing.  The audience couldn't decide on a winner, so we switched partners.  When that still didn't produce a winner, we switched partners again (with girls dancing together and guys dancing together) -- this time, the guys won out, but really, everyone won entertainment value!
