This is in the Microbial Sciences building (where my exam was at).
The Monday of finals week I did not want to study so I went out in -10 windchill
to Natural Bridge State Park. For some reason nobody else thought it was a fun idea.
Unfortunately, it turns out there's not much at Natural Bridge State Park. Here is the bridge.
I spent something like twenty minutes here (at the park, not in the tree), and then went to Tower Hill State Park. I recommend doing the same if you think you can get a whole day out of the former.
The shot Tower, where they poured the lead down as it cooled

And here is the tunnel at the bottom. One kid (pretty much by himself) dug this out in a summer using only hand tools. Imagine that.
