I hiked a section of the PCT starting at a paved road (mile 652 of the trail) and didn't cross another paved road until 290 miles of hiking later. I tear up with gratitude for the vision of the people who worked to protect the land and create the trail.
Also, sure, there is awesome gorgeous hiking in Europe too of course, but, say, in the Alps, mostly it's managed more tightly. You can't just hike for the day and set up a tent where you get tired. Camping is much more restricted to right next to the huts/refuges or not allowed at all.
