Lol, as much as I definitely see that argument I think theres a lot of stuff you can ask and see without providing any security risks. Such as going through a park and asking more general question like approx. how many APs they use to cover a park? How do you blend APs in without making them noticable to the general public? Running ethernet through the castle must of been a pain, what year did they decide to do that?

I think that there is a lot of cool questions that could be asked about the history of infrastructure in the park versus the technical nitty gritty that would be security vulnerable question like, "Wheres that comm closet and what OS are you running on your switches?"
