Since some have been following this, I will let you know what we've decided.
Ohio says they send ballots out a month before the election. That would be around October 5. We embark on October 3. Our daughter can watch for it and forward it, but of course we don’t know exactly when that will be (possibly Oct. 8, 9 or 10). Now, I’m thinking that she might possibly be able to get it to Seward by Oct. 14 by FedEx. If that will work out, we can just pick it up at the Seward FedEx office and then return it. That's the plan, anyway. Thanks again, everyone.
