Step 2: WHEN and WHERE:
Typically the fischertechnik convention takes place in September, and the precise dates are published at www.ftcommunity.de.
This year, the Convention took place on Saturday 9/20/08. Dedicated ft fans (who refer to themselves as "freaks") gathered on Sunday 9/21/08 at Haus Hildegard.
The ft Convention has been hosted in Moershausen Homberger Germany, a small village in northern Hesse. Moershausen was chosen as the location for its central location, as attendees visit from across Germany, Belgium, and the Netherlands. The Convention is held in the fire station/communal village house.
One recommendation I received, is to fly into Frankfurt am Main (FFM), then travel by train with Deutsche Bahn (bahn.de) from the Airport to "Wabern (Bz Kassel)". (via Kassel-Wilhelmshohe) The Wabern train station is around 10-15 km away from the exhibition. Convention attendees have been willing to pick up visitors at the train station.
