Man, I've been in their underground part, every 5 years they open for public and open the detectors themselves. It was by huge margin by far the best executed engineering of any type I ever saw, and I don't consider myself a nerd in this area. Every tiny detail was simply perfect, not a speck of dust, all cables aligned perfectly etc. Seeing inner parts of these massive detector tubes (maybe 10x20m ?) was the pinnacle of the show. Pictures simply don't do it justice. One can't replace physical travelling and experiencing things (and people) for whatever purpose and this shows it well. That being said, since I live not far from there, I certainly hope that containment is flawless, don't want to experience matter-antimatter annihilation of non-trivial amounts anywhere near my kids, or myself for that matter (NIMBYism at its best, get your damn antimatter off my lawn!)
