Koppenbrink begins to perform the COOP.WALK with the "Hessische Radio" in 2002. She goes on in small towns as one of her best pupils, modest and demanding at the same time. Contacts and challenges come up within different hindrances on her way. At first she has to collect experiences, come face to face with realities, improve preparations, hope that support will join her visions.
Her purpose, to be on the road all the time adapts reality and changes into the idea of separate COOP.WALK trips durig the warm periods of the year.
