It's been advertised in the media that he is coming to the CDC. The fact that it's Friday afternoon tells me he's on his way to his Florida golf tournament.
A couple of months ago the Pres. and VP were in town and there was very little heard on the scanners. My guess is everything went smoothly. I wouldn't expect anything different this time.
I would expect to monitor Cobb, GSP, Atlanta system... please respond with any others that would be applicable.
