    So far, no problem experienced, moved to Delaware 2 years ago, so it's the only post office nearby.

    I like the woman that work there...I'm worried that my dad is taking MY certified notice up there and is trying to pick up my mail! Will they give my dad my letter. Its not my dads mail, my father will open my mail and its against the law for my dad to open MY mail.....I hope they don't give it to him. I can't even call up there ...bc the phone number is a fax number.I just need to know will they let my dad take MY CERTIFIED NOTICE IN THE POST OFFICE AND PICK MY STUFF UP? HES JUST GOING TO BE NOSEY, OPEN UP MY MAIL AND LIE ABOUT DOING IT....SAYING I THOUGHT IT HAD MY NAME ON IT. HES BECOMING A LIAR.
