@boys3 no need to apologise, it is interesting how you can break it down in different ways.
I live on the South Hams/Teignbridge/Torbay borders so I tend to look at them as when shopping I tend to go to Totnes/Newton Abbot/Torquay, then I look at Exeter and Plymouth as if I am going to a city it is one of them. So you could say I'm not taking a very broad view and at the moment I'm not going anywhere!
I think the South Hams blip might have been connected to Torbay, for most of the pandemic Torbay has done well, although it was one of the early hot spots due to skiing holidays, but the October half term triggered a big upsurge, I went into Torbay on the Sunday at the start of half term and it was like August Bank Holiday Monday but without the advantage of people being on the beach. It was quite a rainy, miserable week here, bars, restaurants, arcades etc were packed and over the next 2 weeks the numbers soared but they have really tumbled since, figures hitting over 70 a day at one point but in the last week I think we have had 2 days in single figures. Lots of people cross borders, like I do, and South Hams people quite often come into Torbay for schools, particularly the grammars, and some Torbay people go the other way as the don't like the two teir system so infections spread.
We had lots of holidaymakers in the summer but I think numbers were lower all over the country and people were outdoors enjoying the weather so it didn't seem to cause an issue.
Anthony Mangnall is our MP, he was one of the new intake last year and generally seems to tow the line, voted against holiday meals for FSM children for example, but he was one of the rebels this week. He isn't a patch on Sarah Wollaston though, she was a brilliant MP. An experienced doctor like her could be very useful now.
I understand Cornwall are now worried about Devonians crossing the border to access pubs with tier 1 rules and the police have put on special patrols to deter them.
