Love my sneakers

In last 3 years I helped organizing an event called Rhinland Rhetoric Retreat. It goes from Friday evening to Sunday afternoon with different workshops related to rhetoric and communication. We had to change locations twice and this year we were based at the Adventure Centre. The centre is more like a youth hostel with a lot of space and seminar rooms. On one of the walls this was indicating the place where people should put their shoes before entering the center. Cool !
