Here is an apparent response:
"However some idiots have written stupid things, calling into doubt what he is doing out here, which unfortunately get to Rob. Why he listens to these people I don’t know but he does. I won’t respond to them individually here but if and when Rob makes it to NYC I will name and shame those individuals for attacking an individual who is openly and sincerely doing something they are entirely incapable of doing themselves. We have been easily found by several people already by locating us on the tracker map on this website. We are out in the open doing something without guile or manipulation, and to accuse us or Rob of doing anything else is a very low thing to do, and completely without basis. Anyone who doubts the legitimacy of what Rob is doing is free to find us and follow us and to see for themselves what Rob is achieving. If you’re too lazy to be a witness yourself, then, from someone who has witnessed hundreds of his miles already, please have the self-respect to keep your doubts to yourself – or risk the chance that those doubts may one day turn around and bite you on your nose. We’re in Mark Twain country here in Missouri and, as in so many other instances, he made the point better than I could: ‘It’s better to keep your mouth shut and appear stupid than open it and remove all doubt’."
Just to be clear. This excerpt from his blog is before I started this thread, so it would not be a response to this, but it does indicate there is plenty of doubt, and maybe other similar experiences out there.
