It is irrelevent. The PAs won't let you anywhere near.

It was a church over on 16th street that they were filming at. Until April 16th they are filming in the Mt. Vernon/Hybla Valley Area of Alexandria, VA. The staging area and production trucks are about 1 1/2 blocks from my house and its a awesome site to see. Most of the filming is being done around Mt. Vernon Estate and some of the other nearby historical places until the 16th.
