Mark our first guest watched a large black cat on his train journey in Cheshire, while Billy, our second guest, got a good view of a black panther from the front of his freight train in Yorkshire – he found other drivers had also seen such animals. Our guests describe both the close-up and the changing views they got from a moving train.   By coincidence, both guests are interested in the topic of sasquatch, so compare their experiences with the study of North America’s great mystery creature, and consider how big cats and sasquatch can challenge our comfort zone.       Word of the week:   General Impression of Size and Shape (GISS), (see also episode 14) 22 May 2022
