That's a shame. Drew University, Madison, NJ began as the "College in the Forest". I (we 1990s) did tree survey and mapping as part of the archaeology of Mead Hall there resulting in metal tag labeling many of the large trees around the recently fire-repaired historic hall. The chairman of the 9/11 commission, former Governor Tom Keane was the president of the university. Woody Allen's wife also attended there. There are some truly wonderful trees there, two large copper beeches in front. I think I read it's where the first roses from China were cultivated.
