I mow my lawn tall all year. They only time I mow any lower is in preparation for overseeding. In areas where mold is an issue, I think mowing lower before winter may be a good idea, but in more arid climes, I don't think it's needed. If NE is for New England or North East, you may want to mow low, but if it's Nebraska, I don't think it's necessary.

The concept of mowing shorter only applies when seeding.

Here's something to think about. If everyone mows short to reseed every fall, then people get in the habit of mowing short in the fall. Some people will forget that the reason they are mowing short is to reseed and will mow short even after they reseeded. Interestingly, the parents will pass these habits on to their children.
