I was out at the FAR site helping out with a SStS static firing and took my son along. It was his first time to the site and I think he loved it. I certainly did. I had a lot of fun watching him explore the area. He scoured the facility looking for "treasure" at one point I looked in the back of the van and found a pile of this treasure consisting of a broken cinder block, a one inch iron rod, half a dozen rocks (one of which was cool enough that we actually brought it home), and various nuts, bolts, washers, and pieces of scrap metal. We saw a couple of launches and a few static test, all in all a good day.
