Ok, just in case there are people who want to join the tour but do NOT partake in the Frith Forge Conference:
The tour starts from the venue of the conference which is here:
KiEZ, Zum Inselparadies 9-12, 14542 Werder (Havel), Germany
That is about 50 kms south-west of Berlin centre.
Please go through the tour, there is one page for each day with pictures and a description of what is planned for that day..
