52 States in 8 Months

Bike trip to Pennsylvania

Posted in Newark, People by Ulf on November 15, 2008

This morning I used to work on my bike once again as the chain came off twice yesterday. So … once the bike was fixed, a test drive was required. Therefore, Jaume and I decided to follow our little creek here up to Pennsylvania. (Jaume is a math professor from Barcelona who spends one month in our group here in Delaware. He currently works on a paper about differential flatness which Susi wrote during her study thesis.)

The stone you see on the first photos is a landmark between Delaware and Pennsylvania (actually, the border to Maryland is nearby, too). As you can see on the map, the border between Pennsylvania and Delaware is a 12-mile-circle while the border from Pennsylvania to Maryland is just a straight line. Did I mention that Jaume is a mathematician? *g*

Although there where many beautiful places that we went by on our way back, I only took a picture of an invisible fence. Stupid me, how can I try to photograph a fence that can’t be seen?bild3455
One last thing: Are there any good biologists/zoologists among you? Elke, Jens, Moritz? How is this fruit called? I’ve never seen it in Germany, but it seems to grow here everywhere:


PS: The bike was just great today! Although we had some high speed downhills on our way (and therefore also a couple of ascents with high torque), the chain never came off within the 2,5 hours. That is a new all-time record for me on that bike. Only once my back wheel slid away when I had to brake so hard that the wheel stalled (my bike only has a back pedal brake and no hand brakes, therefore the brake force cannot be distributed to both wheels).

    Ugh! That looks gross! Are there any nuclear plants around?!

    Well, the Three Mile Island nuclear power station is not very far away. Maybe these fruits are the outcome of the 1979 incident?

  3. […] About 10 miles further down on my way to New Castle, I saw something which I thought would just exist in the Internet. Have you ever bought books from Amazon.com? For me, Amazon is THE e-commerce company per se. Still, they even have a real building and a real signboard in front of it: From Amazon I only had to go another 3 miles or so to reach my destination. New Castle turned out to be a lovely looking, historic town. And they still have the courthouse which is the center of the 12-miles-circle (earlier in this blog). […]

    Your fruit is an osage orange, also known as a hedgeapple. I grew up in that area, and as a kid, when we played army in the woods, the osage orange made for a fine pretend hand grenade.
