I know it may be too early for this, but it is never wrong planning in advance .Look for someone who can pick me up in the area Koblenz, Bonn, Frankfurt on the Main or Cologne. On the 20.07.2018 I'll write my last exam ending 12:00 a.m., I hope this will be no problem for you. After finishing it I can be flexible to the wished meeting place you want if desired.
You'll get great company with a relaxed metalhead.
