Two upcoming trips that I plan to bring my concertina along if anyone wants to meet up:
Camarillo, California, September 15 - 18 (my wife has a business function, I will just be along for the ride) and a vacation in Northern Europe in October:
17 - 20 Copenhagen
21 Lübeck
22 - 24 Hamburg
25 - 26 Eindhoven
27 - 29 Amsterdam
I have already been in touch with Adrian in Amsterdam and am trying to reach Jim in Denmark.
If anyone is near any of these places and wants to get together and play, let me know.
