Every time I see a link to a video about some dialect or accent that I might be interested in I am disappointed -- angry, in fact -- to find that it's just someone talking about that dialect or accent in some other dialect or accent that I am not at all interested in. What a waste. After that I avoid all video/audio for a month or so until -- fool that I am -- I get tricked again. Is there some secret place on the Internet where an interested person can listen to ten uninterrupted minutes of conversation in a rare dialect, or do I need to become an enthusiastic traveller (unlikely)?
