Brad Paisley's latest single 'Southern Comfort Zone' may be more than just great music.

Last night photos of Brad hanging out with people in Portland's 'Old Port' were surfacing on Facebook, then on Brad's 'Lockerz' account.

Here's what he posted: "Outside my southern comfort zone mastering the album up here in Maine. But that's the point."

And here's a photo of Brad hanging outside of Gritty's in the Old Port.

If you see him, tell him we say hello!
