Well, within the 25 years that I have lived in Europe I have seen quite a bit of Europe and I always loved to see new landscapes and to explore flora and fauna outside of Germany. There are so many places where I went hiking, especially in Countries that are close and a short drive away from Germany. I have been to France, Italy, Spain, Poland, Austria, Germany, Switzerland, ... you name it. But I always wanted to hike through the Appalachians.
The east coast of the United States is pretty densely populated, with cities like New York City, Philadelphia, Washington D.C., there are a lot of people confined in the bigger metropolitan cities. But outside of it you will find a very unique looking landscape.
The hardwood forests of Pennsylvania and Upstate New York, for example, are abundant in wildlife... I have seen deer, chipmunks, salamanders in such a short amount of time. Watching the lightning bugs at night was also a very pleasant experience. It is hard to see them nowadays in Germany. I was a young kid the last time that I have seen them. And it brought back some good old memories of my old Heimat...
I drank water out of mountain water springs, explored the local flora and fauna, ate wild strawberries, raspberries and blackberries, I have watched a lot of wildlife, and enjoyed the natural forests very much.
I have seen a lot of rare herbs and plants, and enjoyed being away from people in a very rural place with a lot of lush and green, and more importantly, water as an abundant resource.
