I'm only familiar with the western half of Hwy 30. One of the kids lived along it. I much prefer driving through the towns along the way rather than I-80. Pretty country and interesting places, too.
If I am going from point A to point B on business or to a vacation point....it's the interstate for me
....BUT..., if I am out to just enjoy a drive to some distant place at a leisurely pace, it's the back roads and old 2 lane roads where just about every cross road has a name, a country store and is the center of some small community. I love to stop for some made up reason and just strike up a conversation with who ever will talk to me.....my wife hates my spur of the moment trips to no where in particular, at no particular pace, for no particular reason, to see nothing in particular.
