Your memory is excellent Oliver. Well, the oddest thing I found out at the talk was the path was surprisingly popular with Welsh sheep drovers, which, geographically speaking, doesn't make a lot of sense. It may have had something to do with the toll road network and that it was cheaper to avoid the more direct routes in through west London. There were other little nuggets of info too which may turn into future tags.
