There's a pandemic going on. Having lots of people gathered in one place in one day isn't a good idea.
My polling station handled it very well I thought.
Relocated several polling stations to allow for bigger rooms/more space.
Enter and exit building on different sides.
Workers outside to help with spacing, marked waiting spots close to the entrance and within the building.
Hand sanitizer at entrance to building and voting room, masks required, every individual given their own new pen to use (and take with them so no reuse), plexiglass screens for all workers, well spaced voting booths.
The only thing that would have improved it would have been workers cleaning each voting booth between uses. The site had wipes you could take to wipe yours down, but that did require voters to be proactive. I think I was the only one I saw that did it.
They also had curb side voting which allows folks to stay in their car - usually for disabled, but where allowing high risk and older folks in general to do it.
