Jeroen Pleijsier a.k.a. Prik is putting on a flatland jam in Rotterdam. The jam is called No Licence jam and will take place on 4 September next.
The event will take place on the "Schouwburgplein" which is easy for the foreigners asking for directions.
If you don't have a licence and travel by train, make sure you get to the Central Station (CS) at 12:30pm. Someone will be present to show you the way to the jam circle.
In case you need more info, got to the [url=http://www.010flat.tk]010 FLAT website[/url] and ask Jeroen all the questions you have and that should include how to pronounce the word: Schouwburgplein.
