This is a location that I was privileged to visit many years ago, when very few people were allowed access. Since then it's been opened up to the public and had many more visitors.

Twenty questions should be enough as I'm only trying to get the name of the location, not a precise point within it. I should warn you that I'm starting a new job tomorrow and may not have as much time as usual, but I'll try to answer questions as promptly as I can.

To confuse everything alternate posts should guess firstly about the location and secondly about the new job!

It's no good asking me about the new job. I'm not sure what I'm supposed to be doing.

I've been doing my job for thirteen years, and I'm still trying to work out what I'm doing. All the best for it, anyway!
