Know there were a few heads who enjoyed this. Won't call it series 2, as rather confusingly it isn't advertised as such, in fact I didn't see it advertised anywhere, caught it by chance. Anyways...episodes so far have covered Maes Howe, Uffington, Druids on Anglesey and I missed the first episode, but guessing it's something to do with Picts. They seem to be repeated fairly frequently if you've missed em thus far. Won't tell you anything you didn't know already, but it's a nice way to kill an hour.

This is worth a listen too. Good Ole Ronny Hutton on it.
