I just helped load my t-trak modules for this show. I will not be there for several reasons. But a few members of my club will be there with a much smaller display than usual. We have set up at this show for over a decade. There is usually over 1200 people attending, and it is two full days. This year the temps are supposed to be just over 90, high humidity, and no air conditioning. The buildings are just regular county fairground polebarns, with all of the rollup doors open. It is usually hotter inside the buildings than outside. The normal smells of the attendees are enhanced and refined with the high heat and humidity.
It is usually a very good show, with plenty of n scale bargains. But one of my main worries is this show will draw people from many hours away. It doesn't really matter what the covid rates are for Allen county, or any neighboring county.
The artical mentions many people driving for 3 or 4 hours to get there. They could bring it with them from out of the area. And the extra heat could mask some of the covid symptoms, assuming that symptomatic people would stay home anyway.
