Finaly the location is fixed: The Camping of Calonge, close to Palamos, about 80 km north of Barcelona:

There will be no problem to hire a bungalow if you don´t like to carry a tent with you.
The colleagues have planed a little ride with 365 corners in the line
(I´m sorry, not able to load up a picture of the map)
If there is anybody interested: The following Weekend there are two interesting events in Spain, the GP in Jerez and the 40° aniversario of the first Moto Grand Prix at the circuit of Jarama/Madrid. I allready have decided to go to Jarama

Would be very nice to see anyone of you!
