In reply to Wiley Coyote:
Perhaps he was filming a video for his daughter, who because she just lost her job can't come over to the UK for xmas this year and won't be able do their festive walk together. Perhaps his wife suggested that he get out and take some footage while the weather is good because now that his health is getting worse, he might not be able to do it in time, should it get much colder. If he does it this week, it will also be cheaper because it can go by sea post, together with the sweater the mum is knitting, and a bit of cash she saved.
Maybe he is making a tribute film to share with his pals, now that one of them can no longer walk their favourite ramble due to a serious condition. They hope to laugh and reminisce together over some beers next month.
Maybe he is just a dickhead?
