The Afternoon Blues

We've got the blues, the afternoon, it's too hot for anything, blues.  Mornings with Daddy seem to go well - full of grocery trips and some outdoor time.  But after naps (which haven't been very long recently), we are struggling for ideas.  We just get bored!  So this is my plea for suggestions!  We are even pondering a family gym membership because of the childcare and pool.  Let me know if you have any ideas - games to play at our house, or free/cheap places to go on adventures!  This mom, and Owen and Olivia desperately need some afternoon entertainment!
