I am 1000+miler and was planning another section hike next in May from the UK-Daleville to Harpers Ferry. I get the impression that Partying groups are very prevalent;even on YouTube saying how contact is inevitable. I did came across one instance when I was last over there. I am no prude- I was in San Francisco in the Sixties-just don't want it now. Coming across music booming out would not suit me.
Can I avoid it by keeping away from the shelters and hostels. I very rarely slept in a shelter but meeting other folk was fine for a chat and water.
I could go on the PCT or the Colorado trail but I do have AT fever.
