Hmmm...
Britain is great for riding, but I've been all over there. I'm gonna miss it but it wouldn't be the first place I'd choose now.
The Nordics look great for scenery, but from what I have heard the speed limits are tightly enforced so it might be a bit short on thrills.
I would go for southern Europe, but add in Germany and France - maybe head out to Eastern Europe too.
Don't really fancy USA/Canada.
I intend to get around as much of Oz as I can while I am here.
