Comments

Just a note to say that we've disabled the comments section, and added an email link to us at the bottom of the page.

For one thing, it turns out that I'd mistakenly put the wrong email address for comment verification, which explains why many were not getting through. (It doesn't explain why some of them were, however).

An additional reason, is that comments sections are really intended to generate a discussion among viewers, which isn't relevant here.

We are back at home, recovering, and will be posting a few more follow-up postings about the trip, as we decompress.
