Sounds like a great trip. I think we will have to sit this one out. I had a friend (N4DXC he's now a SK) that made 3 trips to Alaska on he and the YL's bus. We stayed intouch with him via 20 meters mostly. That was awhile back. The way conditions are these days, we would probably be out of luck. Hope you have a good time and a great and safe trip. Maybe you will catch anpther ham traveling that direction about the same time.
By-the-way, welcome to ORR and thank you for posting. If you have a computer with you, please keep intouch along the route. We would certainly enjoy hearing from you and sharing your experiences.
