Currently one of the best programmes on TV, not that there's a lot of competition of course with all the rubbish around. It is very addictive waiting to see if any unknown location can be identified by the viewer, I did once and emailed TPTV with the info, I might get a mention in a future episode. Not to be missed by curious people who can also learn something from each episode. If a TV programme or film can be judged by how long it seems to last, for bad ones time drags by very slowly and for good ones it flies by, then this is the best TV programme ever as the hour goes past in what seems like just five minutes. I spend more time watching programmes on TPTV than I do every other channel added together but this might be age and nostalgia related.
