The guy in charge of planning for Obama was a little shocked, they all planned to have multiple ways to get anywhere, it’s just how they roll.
Yes, but my point is, you’re talking a half-hour flight vs a two hour drive, for arguments’ sake. If he had other stuff planned that was within that extra hour-and-a-half either side, that was a higher priority, then he can’t do the road move. That might be poor planning or bad priorities, but not necessarily a call he made. A more impressive POTUS, of course, would have a brief on the plan for the day and might intercede on the lack of a viable road option, anticipating how this looks!
