Anyone done the International Selkirk Loop?

Hi all –

We're exploring doing the International Selkirk Loop (USA + Canada). As I've researched it, it seems to have a lot of highway riding without a great shoulder. To be fair, I was using Google Street View to assess the shoulder on the highways.

If you've done it (or parts of it) – was it a good bicycle touring destination? Do you recommend it?

Thanks!
