The sign art was made entirely out of old road signs: the people at PennDOT made them into sculptures and murals around their office and along the road. Here's an online presentation about the art and some other pics for you (we didn't take any). If you happen to be in the Meadville area, you should definitely stop by and have a look at this art installation; it really is an amazing bunch of work.
Now for the mystery. When we got home from this road trip, I was surprised to see was a FedEx delivery notice thingy waiting for me. Apparently they require a signature for a package.
The thing is, I don't remember ordering anything that would have shipped last Monday, and I'm not sure that anyone sending me unexpected stuff would do so via FedEx because it's expensive. So I'm confused - not to mention hugely curious - about this package and its origins. What could it possibly be? Did I order something ages ago and forget about it? Is it a present of some kind? I just don't know.
I'm going to have to make myself wait to pick up this package until Tuesday because I don't want or otherwise need the car tomorrow. Fortunately, the package is being held at the main facility until Tuesday night so I should be able to sign for it that day. Until then, I live with this mystery.
