Fort Henry
From the moment we arrived, it was clear that these guys were ready for kids. Cameron and Zach were immediately enlisted in the British military, donned uniforms, and got basic drill training. Kayley decided it was all to intimidating, and opted to watch instead.

And of course, our kids just had to spend a little time in in the slammer, with their very best bad-guy impersenations....
