At our election I just walked to a nearby school which had the voting and waited in a queue for a while (it was unusually slow this time because of some changes in how the voting process went) in the end you hand a person your vote and they cross your name of a list and then they put the vote in a box.

There were three different lists and boxes in the voting room but everyone got mail beforehand that said which list you should go to.

All in all, it went very smoothly.

Also voting districts are only used for statistics and logistic purposes. So the insane practice of gerrymandering doesn't exist.
