Seriously, I think that you will need a support pillow on the plane. I wonder if your back is going to be able to handle bumpy rides, especially if you are in a Jeep. Could this bumping bother your fusion?

The last time I canoed, I had a good back and was not sick. The only thing I can remember is paddling made my back and especially shoulders tired...

P.S. Have you mentioned this trip to your back doc?
