It's interesting to see the placement on I5 north of Sacramento. Corning was always a problem on holidays, but rather than add spaces to Corning, they added two new 8 spot stations, one 60 miles south of Corning (so it's a better fit for SR drivers coming from San Francisco), and one 20 miles north of Corning (I barely made it there, but it was cold and I had a lead foot)
