Just reflecting on Dans Day 4 and where he is now...it's dusk in NSW and he has approx 8-9 hrs riding in the dark ahead of him, with some rain likely. It will be a long night, but knowing the end of the ride nears he will be focused on ensuring he rides to finish. Plus it sounds like he has the support of the LD Riding community out there, literally (look at all these intercepts!) to give him wings.
I see TJ looks like he will be out an about in the wee hours of the darkness and I have not doubt there will be others.
