Yeah, I don't think I could hang with the Walk About Love group for too long, either, but it's neat to see all the different ways people use the INT. You'll likely run into people doing section hikes, school groups on educational trips, kids doing the trail (with parents) in connection with their bar mitzvah, political people trying to further an agenda, charity-oriented types walking to raise money, and spiritual seekers hoping to find enlightenment or something.
Obviously it's like this, to an extent, on all long trails...but in Israel I think hiking, and the act of walking the land, has an inherently different meaning.
