Just got back. Stood two hours in line, there was still a two hour line when I left. New electronic machines that didn't register your vote, just printed it to hard copy then that went in a scanner to count. So technically, there is a hard copy paper ballot if there are issues/ discrepancies.
Heard stories of five hour waits the next town over.
The voter rolls are also electronic this year. You don't have to vote in your own precinct, any polling place will do but once you've signed the rolls all the polling places can see it.
