Patrick Bouffard is giving a HG workshop for advanced players in Agatharied, Bavaria, Germany 26th-29th March. The workshops for beginners and those with a bit more experience will be given by Ulrike Fritsch and Silke Reichmann de Salas. In addition, there will be accordian, bagpipe and dance workshops.
Details (only in German though): http://www.spielkurse-agatharied.de/kurs_akt.html
You have to sign up by 29th February and transfer the money at the same time to secure your place.
The workshops costs EUR 156, accommodation with full board is an additional EUR 90 (you have to bring your own sheet, duvet cover and pillow case).
It's quite pricey, but I decided to sign up anyway as I'm sure it'll be well worth the money.
Agatharied can be reached by train from the main station in Munich, the journey takes about 50 mins. From the station in Agatharied it's about 20 mins. to Berghof (a kind of youth hostel), where the workshops will be taking place.
The area around there looks really beautiful, so if anyone has the time they could combine the workshop with a holiday.
