Yes, I visited in 2001. I was at White Sands Missile Range for official reasons and was very fortunate to receive a private tour of the area - including the blast site. I was also encouraged to take a small piece of trinitite home with me. I've tested it with a geiger counter and it's not much more radioactive than normal background radiation. It's pretty cool, but I wonder what it would fetch on eBay?

To get there, I started at the base close to Las Cruces and drove north through the range - no missile tests that day. It took almost 3 hours one way, but well worth it. I would encourage others to visit if possible.
