There is a ballot tracking system as well, I can see and be notified as my ballot moves through the counting system. It's pretty cool.

I actually just got back from dropping off my local elections ballot 15m ago, quick bike trip maybe a mile or so away and back.

Of course, because it makes it easy for people to vote, the republicans want to do away with it. If you have to stand in line for several hours (which seems to be very normal in most cities) and potentially miss work to do it that's going to all but guarantee that working people and the less motivated will not vote.

So yes in places that only do in person voting, national or state holiday.
