Now, I'd love to say that my kids learned everything there is to know about the time period today, but that's not quite the way these things work. As educational value goes, we learned a lot about torture and punishment during the times by exploring their "dungeon." That pretty much covers the total educational content.
In my opinion, though, field trip days have a far more important result. Time together. Time together focused on one another and on a mutual topic. Shared experiences. Memories.
We were surrounded by kids from school groups, and it made me sad to know that the parents of those kids were missing out on that special experience. I'm so grateful God called me to a different path.
