Mandatory Fun? We headed for Casper just last weekend for family day for the Army. Or as some people like to call it Mandatory Fun Day. They had family day during the Drill weekend and it was really fun. They had hamburgers, cookies and bunch of games to play. Kennedy had a great time. She was able to play with other kids and they even had a dog. The family day ended at 3pm. When it was three people left like a fart in the wind. I was happy to go. They put up up in a hotel and I got to watch cable and hang out with my husband. It may have been mandatory, but I was glad that I went.
