Media, the President and that Baseball Visit

Apparently even impromptu visits such as the one the president made to the Little League baseball game this week are planned out in advance - not much in advance, but the only people who didn't know about it were the press corps as this WashPost article describes.  I can also speak from personal experience that when Michelle Obama came to my school a few years ago, we only were asked six days in advance (the idea was around much longer, but they hadn't selected a school), but from that point on the Secret Service was basically camping in the school to make sure everything was all set.
