I think you have to come here first.
Laws here are only relevant sometimes, if it suits the locals.
EU stuff...well....who knows.
I heard that this year is last of the olive producers EU grants. What will happen next year.
Olives were 0.96€ kilo 6 years ago they were 0.33€ if you could get it this year... Dont rely on making a living from the finca. In live on an organic farm producing my own needs apart from petrol and gas and the odd bottle of beer and wine, and straw for my donkeys.
What do I know?
Go for it and enjoy :)
