Web special, hour-long preview of Series 22.
Footage starts around 6:40 into the clip below. Includes a bit of discussion about their visit to Australia which will feature in Series 22. BBC Knowledge will have eps in HD pretty close to real time by the sounds of things; for those of us with Foxtel.
I've been a bit ho hum about TG recently but this series looks pretty good, although I haven't bothered to watch the Patagonia special yet. Any good?
