NOM Central is now in Philadelphia?

National Organization for Marriage sent out an email blast signed by Brian Brown. The email is about some nonsensical support of that fried chicken joint but I caught the following paragraph:

At my own local Chick-fil-A here in Philadelphia, I was struck how the turnout reflected the breadth and diversity of support for marriage in our community. ...

I thought that Brown was surrounded by the proverbial white picket fence in the Washington suburbs. While NOM still shows the Washington DC address, I noticed this on the bottom of their "about" page:

Processing Center
P.O. Box 28925
Philadelphia, PA 19151-9900

Eventually, we'll sort it out. NOM has used numerous addresses over the years.
