Massive gathering in Germania in 2009

[Tib. Gabinius]

Hm perhaps also a question of the traffic and the possible places.

If it would take place in the area around Cologne (CCAA) and Bonn (Bonna) theres an airport (Köln-Bonn), trailways and a number of highways which help to arrive the area easily.
It would be also a historical place of the campaign against the bataver.

Also Trier (Augusta Treverorum) would be a good place, even for the later romans. Also there some highways leads to, and an airport (Frankfurt Hahn) is not too fare away, also it isnt "next".
Xanten (Ulpia Traiana, not ! Vetera) and Kalkriese also would be nice for somehwat like that event, but i m think both are not that good to come to.
But the background of Xanten would be real great...

That just for a little organisation view
