I'm not overseas, but Ed Henry of CNN (@edhenrycnn), Christina Bellantoni of the Washington Times (@cbellantoni) the lovely Michael Scherer of Time  (@michaelscherer) my buddy Jake Tapper of ABC ( @jaketapper ) and the peripatetic Mike Allen ( @mikeallen )  are all tweeting 24/7.  Follow them as a group on #preztrip. 

And remember: I'm @marcambinder. Less buttoned up, more casual... and always on the news (not on my breakfast.) 

In other SMS news: the U.S. government has set up an SMS delivery system to permit folks around the world to respond to Obama's message tomorrow. U.S. citizens, apparently, can't access the system. (Btw: won't the National Security Agency be monitoring the incoming texts to see if anyone stupid enough to threaten America leaves tracks?)
