Thanks for the invite.
We live in Norway, and have visit Corsica 3 times on vacation in '08, '09 & '11.
And we'll be back! (But this summer we had a fantastic caravan vacation in our country.)
Did rent a car, and have driven (almost) all over the place from Corte and up to the north of Cap Corse.
A god place to eat dinner we would recommend Bar Restaurant Le Bartavin! In Patrimonio.
