If I understood the brief report on this subject correctly, the President will be in the Allentown area on 12/4/09. I think it would be interesting to monitor the activities, but there are so many frequencies that could be used it seems like a giant crap shoot to pick the correct ones! Does anyone want to make an intelligent guess on the most probable ones that I might want to listen to? I have a list of LeHigh County, State Police and there is a massive list of Federal frequencies on this site but which ones to choose. Thank You!
