Today is the end of the first week in Berlin and I could not be more tired. If I stop drinking beer, I might actually lose weight on this trip with the amount of walking. Since Wednesday I have seen so much. Some of the cool things I saw was the Natur-Park, Tempelhofer Field, and Teltow Gartenstadt. The Natur-Park is Berlin’s version of The High Line in New York City in the sense that it is on an old rail line. The Natur-Park is also all wild growing and the grasses are kept low by grazing sheep. Tempelhofer Field is an old Nazi airfield that has been closed since 2008. Since then it is used for all different kinds of recreational activity. It was cool too so many people use it for different activities. This was a fun site to visit with the tour guides we had because they let us take us turns using their bikes to ride up and down the airstrip. Out of everything we did the second half of the first week, I enjoyed Teltow Gartenstadt the most. This is a neighborhood that recycles 100% of its rainwater. All of the rainwater that doesn’t go through some of the permeable surfaces, all flows into a lake. It was very interesting to see a site like this given my interest in ways to improve the environment. It made me wonder why there aren’t more neighborhoods built like this.
