Wrt to worrying about contracting infections in London, I personally would be far more worried about using the ‘Sewer Trains’ (you, gentle reader, may know those better as ‘the Tube’) than about being in the warm room in which the pen show is held.
Ok so I am a rural FrootLoop with twigs in his beard, and as a Midlander I’d be thinking of going to the Birmingham Show in June anyway, rather than to the one in London in March (the Birmingham show’s location is just across the road from one of the exits from the main railway station in Brum).
But the Tube is hot and horribly crowded and carries Cthulhu knows how many people every day, in one of the most globally-interconnected cities in the world.
To be fair, I suppose I’d just need to wear gloves in order to ride it without fear of any infection, and maybe a scarf around my face if I were feeling especially frit.
Let’s hope that there’s no need to cancel any of the shows, eh?
