From my absentee ballot instructions (emphasis in original):
If you have returned your absentee ballot, but find that you are able to vote in person, the law requires that you do so. You must go to the office of the Municipal Clerk no later than 10:00 a.m. on Election, Primary or Referendum Day before going to your polling place to vote in person."What's that honey? You don't think you're going to have the baby today? Okay, well I'd better head down to the municipal clerk's office to cancel my absentee ballot and let them know that I can stand in line all morning at the middle school instead. No, I can't just rely on the one I sent in. You remember when Henderson up the street got caught mowing his lawn before the polls closed a few years back. Nice fellow, that Henderson . . . I should put in a good word for him with the parole board. Anyway, I'll be back in a few hours, you need me to pick up anything?"
