Mailing time to Midwest (Chicago)

<p>I know Chicago is notoriously bad for mail delivery on time but I'm getting very worried as my status changed last Thursday. It was originally fall grades than went to forwarded about two weeks ago and changed to reviewed again last Thursday and the backdoor links started working (Enrollment worked on Thursday), (RSVP worked on Saturday). I was thinking that it was probably shipped out last Thursday as thats when status changed .. so starting to get a bit worried about how long its taking.. I'll wait to freak out until after tomorrow. Anyone else from Midwest have to wait this long (if it was really shipped last thursday - as in 3 business days + day of shipping)</p>
