Leipzig
I managed to see some nice things on the bike sharing system "Durstexpress". I prefer the name "DursteXtremeMTB" for the purposes I used the 3-speed bike city bike for over 3 hours costing about 5€. I traveled over 40km on gravel and small mountains towards Markkleeberg and cycled around the Cospudener See. This is a lake that was once an open cast coal mine that was flooded in 1993. It's a very popular nudist location it that's your kind of thing too!
I spent 2 nights here in a fairly large and boring hostel full of families and kids which was a bit of a shame and was happy to leave in search of a new place.
This place is also a popular kayaking location with plenty of people on fun boats
On the way out of Leipzig I saw a man taking a shit right outside the train station on top of a power distribution box. It was very unpleased and I had to head straight to /r/Eyebleach to clear the image of it.
