I dunno. If there isn't a yellow brick road, with porto-potties every 10 feet, folks might still get lost.
Seriously, the signs look good.
I was standing on the PCT near Lower Rock Creek Crossing a decade ago, when this guy comes up with map in hand and asks, how do I get to the PCT? My response...You are standing on it. His response...No, really how to I get to the PCT. This went on a couple of more times until I just walked away.
Akichow, they would still be people who would get lost with all the aforementioned plus a neon sign.
