Apparently All the Mailmen Are Going to Lollapalooza!

Hey hey Lolla is officially here and apparently that means you can't drop off mail!?!?!?!

See photo below...huh? What does Lolla have to do with the USPS collecting mail from its mailboxes?

We also noticed the same thing on Plymouth Ct so it must have something to do with proximity to the fest.  Anyone know why they're doing this?
