A bus tour... by airplane?

President Bush has a really unusual way of going on a bus tour, as the Dayton Daily News failed to notice in its own news brief.

Breaking news:  Air Force One has landed at Dayton International Airport, and President Bush's bus tour has left for Hara Arena.  Bush began his Tuesday bus tour at a pancake breakfast in Maumee, outside Toledo.

Err, I understand the reasons for this, but why call it a bus tour if you're traveling on Air Force One?  It's like calling our President a scholar.
