Interesting vlog here and around the 4:30 mark shows it taxying - slowly past Shep's Mound on what was a wet morning.

Sadly, I didn't get chance to view it myself, but managed to get some viewing in at the new Shep's Mound a little later on.
Nice to meet you Grahame too btw and keep up the good work!
