I try to keep up with Free events in our area to take Milo to.  I just came across this event:

Tomorrow (August 13th) The Sacramento Zoo is offering free admission to families.  The Zoo is doing this event, sponsored by Target, and encouraging you to bring a new, back to school supply to donate for children.  That sounds pretty easy & donating generally makes people feel good. I always feel good after I donate to something like that, and you GET a FREE day at the zoo. Pretty sweet deal.  Heres the link to the zoo’s webpage for more details. We may just see you there.
