Take our Daughters and Sons to Work Day -- my husband's work put on a big event where all of the employees and active duty military were invited to bring their kids. The event showcased all kinds of military equipment.
I took our youngest son. Of course, he wanted to hang out at his dad's table where all of the "cool" stuff was displayed. At least, "cool" to a thirteen year old! He was so excited and wanted to take lots of pictures to show his friends - he is sure they'll be jealous!
