Visiting a high ranking facility's network security laboratory, and they asked me what I wanted to see -- any suggestions?

(This might not be the right sub but I'm just looking for any suggestions :)

In a month or so, I'm going to be visiting a nationally ranked facility's network security labs, without no specific areas about where to look at (they asked me what I wanted to see). For context, I'm a 17 y/o rising senior with an interest in computer science. Any suggestions/ideas?
