1. Much of the train trip is likely to be through areas with no cell phone service, and therefore no broadband service.
2. Whatever I get is unlikely to work in Canada except possibly at ruinous rates.
3. I can't afford it anyway, not with the cost of the pickup repairs in Arizona and the pending car repairs here in Oregon. (At least there won't be sales tax on the work and parts.)
Let's see if I can survive two nights and three days without internet access.
