This is what every president does. He goes and visits schools, factories, etc. It’s gone on as long as I can remember. When RWR was POTUS, we lived across the street from a major DC hotel; he and his caravan were there about every other week addressing some group or another.
I personally regret that the person doing it now as POTUS is BHO, but that doesn’t alter the fact that it’s part of the job.
Rather than focusing on where he goes and how he gets there, we might focus on what he does when he is IN the Oval Office. Technically, he’s there 24/7 regardless of where he might be, but more harm is done when he is in that physical location than at a factory or school.
