I recently hosted a photography event on Lulalearn.com. I decided to take a group out to photograph some of the cool U-Bahn stations that are around Munich. The map below shows some of the stations of interest.
If you are interested in checking out the stations for yourself, I would highly recommend the list of stations here. We bought a day ticket and soon found some cool subjects. Lulalearn.com is a great way to meet people with similar interests.
