I remembering visiting the Cornell Campus and being shown where the students jump off (I think it was a bridge, it was over 15 years ago I visited). It was an odd thing to see on a campus tour!
It was probably the suspension bridge
Ithaca, Cornell's home town, is very hilly and full of gorges. So all the bridges at this point have either fences or nets
around them to prevent jumpers.
Heh. Here's a thought: Ithaca is only about two hours from Scranton. In the final episode, Andy could go back to Cornell and "gorge out" over losing Erin.
