Well aside from being 50 years ago, I owe access to those fraternity brothers that explored the campus in the spirit of "where no man has gone before." 😉 I think the campus was less locked down back in the day than it is now.
There were adventures that were not for the faint of heart, or at least afraid of heights, which I declined. I know of one story where a ladder was stored outside of the Great Dome upper level which was subsequently used after hours to access the top of the dome. I that was one trip I passed on for sure.
Fun times, fun times.
