Yepp, wtf belongs to GerTA ? First of all, cause from time to time I'm asked, GerTA is rather virtual. There are no club meetings and we don't organise any trips. That's because "members" live in Hamburg, Rostock, Frankfurt/Main, Mainz, Munich etc. etc. . We try to meet at games, even it is Glasgow or somewhere else. And we use these email things and phones.
Most of us are Germans, but one or the other is Scottish born and only lives in Germany. And we all have friends and connections to Scotland.
