This is on the grad campus. I had ecotherapy this weekend, we had all heard of what the undergraduates call "Narnia". We thought it was a myth, but one day last month, while also in ecotherapy, I was walking with a class mate who was complaining of the undergrads. He was saying they just pop out of nowhere, and they are infesting the grad campus. Just then, two students hopped out of a bush.. so we investigated and we found it. So on this day, I took some other classmates, one of whom first told me about it but never found it. It's pretty cool, just wide enough for one person to walk through.
