Jaimie and her husband on are the road right now, a fifth-wheel, heading for Alaska. She posed the kind of question you are interested in, in this article in June, 2007. We hope that your cancer stays in remission for very long time. April is a bit early to head to Alaska. I would recommend delaying at least a month.
I would suggest that you contact Jaimie directly and ask her opinion. You can reach her current columns and twitter postings from this page. scroll down to the section that reads "More from Alice and Jaimie" and then click on any of the subject headings for contact information.
