Hashing (not: hashish) in Frankfurt?

[sos-the-rope 606]

It recently came to our attention that there’s a plethora of hash (not marijuana) groups in Frankfurt.

 

in case you’re wondering or about to make a terrible joke, it’s about running and boozing with fellow jaded expats, not illegal drugs.

 

Anyone been involved with that? I’ll understand if you choose to PM rather than confess.

 

just wondered if any of these things happen in Frankfurt centrally rather than in the surrounding environs. Are all all the city hashes basically pub crawls?
