Polling observations for Salt Lake UT (daybreak iykyk)
Steady line for voting. Not more than 10 minutes though (Utah is a primarily vote by mail state)
Half of line was for same day registration/provisional voting. Well organized, but poll workers were clearly concerned about wait and were looking for ways to help the provisional voters (not much room for filing out forms)

Live update, they have made a separate line/area for unregistered voters to keep things going. Utah believes in voting 1/

Line looks to be around 25 minutes (people voting after work I suspect)

Utah has electronic voting machines that have an attached paper printer. When you complete your ballot, the paper record is printed in a separate sealed box and displayed for your verification like a light box

Only a couple interactions of note.

While in line, an election 'expert' tried to claim the right to a receipt/electronic copy of ballot so he could prove his ballot hadn't been altered. What he was advocating for was clearly a security vulnerability and sounded like some Lindel/Flynn nonsense. Poll supervisor was polite and even asked main official about it (not possible, see printed ballot explanation above). Luckily, election truther had a buddy who talked him down.

Other interaction of note was maximum cognitive dissonance. Gay couple entered the library with MAGA hat and LGBTQIA for Trump t-shirt. Think the other person had a campaign shirt on, but couldn't make it out.

Apparently turned away by the poll worker, milled around entrance until they got a library patron to take their picture and then wandered off.

Suppose there will be an aggrieved social media post incoming, but showed a lack of audience awareness if they were expecting to make a splash
