Thank you guys !
Garry, the closest that I will get to the DF is Tepostlan . I've been to the DF several times and I love it, but doing it on a bike doesn't convince me.
Cal, my idea is going through Alberta on my way up and through BC on my way down. I plan to cross into Canada at the end of June . Maybe we run into each other in northern Mexico in late march ; otherwise i will come back to your offer once I'm up north.
Mark, looking forward to meet an other grouch, would be fun not to be the only one !
Gracias y saludos,
