My state, Washington, is all ‘vote-by-mail’. Yes, most counties have a drop-box you can put your ballot in without actually mailing it. That’s what I did with mine, my wife’s and my son’s ballots.
I would MUCH rather go to a polling place and cast a vote there.
I agree about going to a polling place. Since I moved here, I always wonder if my ballot will be torn up and thrown in the garbage. If they don’t like who I voted for for example.
