Fun at the Children's Museum

So Tristan had a birthday.  He's 3 years old now! And in honor of his birthday, we took everybody to the Children's Museum here in Tucson.  We were all prepared to pay, but when we got there, we found out it was free in honor of the holiday! Great present to us! The kids (and grown-ups too) had a blast, as you'll see below, so much so that they ALL conked out on the way home, as you'll see in the second picture.  All in all, a great day!
