The video has a very good analysis of the rail network and questions pertaining to agriculture. What is particularly telling is the comment section. It is overwhelmingly separatist (or pro-join-the-USA).
Joining the USA is, in my opinion, the backup plan. We need a new independent prairie country. That new country will either be a republic or a constitutional monarchy (a member of the commonwealth). I support the latter view but recognize it is a conversation that will inevitably be had. If the bold separation experiment goes sour on us ... then we can join the USA.
