Dearest X,
I realize you're thinking of a trip specifically in the Northern Hemisphere however as a thought, you're more than welcome to come down our way & am more than happy to have you has a guest.
The reason I am suggesting coming down this way? Umm because it's a completely different continent, country and just a nice place to bike.
Even if you don't want to come down to Western Australia there are many other cool places to bike in Aust & NZ.
I will throw out more idears later.
