We used similar methods to those used historically to assess railroads and interstate roads. If you're at the center of a bunch of track with spurs going off, you're highly accessible.

Interstates and parkways ... we recommended going to 70, and some of the four-lane non-interstate, non-parkway roads we recommended going to 60 miles per hour from 55. Many of the rural interstates are now six lanes and not four lanes like they were at that time, which, in my opinion, makes them even safer.

They leave the insistent monotony of the interstate for more reasonable roads. While the former slices its path through entire states, peppering them with exit signs and mile markers, these lesser cousins of the grand highways keep their manners intact, clinging gently to the hemlines of all but the most obstinate geological points of interest. Charming and sometimes a bit frightening, their paths are as unpredictable and winding as a little boy's route home from school.

The railroads are maxed out.

Sophomore records are historically really difficult.

We sent him to Rush Medical Center to get re-evaluated and assess his cognitive function. It's primarily a nagging headache. These things can take anywhere from one, two, three days up to a week. It depends how the symptoms resolve.
