I've typically lurked on here because I find the exploration done by all of you significantly relevant to my focus on urban development and human industrialization. At SMU we have a few pretty cool spots, notably our steam tunnels run throughout a huge portion of the campus and date back into the early 1900's...an old Dallas post of the tunnels documented the older sections of the system. Here is what I consider the most updated glimpse of the system currently since this is on a somewhat more modernized section. The system is extremely difficult to access now....however if anyone is familiar with the Dallas Hall apartment, the views from the balcony are amazing but that's a bit easier to access. From my experience the UT Dallas tunnels are extremely more difficult to access, almost impossible at this time....there are extreme measures to keep students out such as motion sensors, infrared cameras, roving police patrols, and the tunnels have been retrofitted with gates every few hundred feet to isolate sections hindering exploration. To my knowledge, the last true exploration of the UT Dallas tunnels was in 2011.
