Its really fun to tell them things that are wrong, and then they consult there trail maps, and then you go oh I'm sorry, I though you were talking about the OTHER glades. Then you say, since I messed up, I'll just show you the way there...
Then you lead them into some massive double diamond treed chutes...and book it.
Anyways,
I have this one poster in my room and it falls down all the time, and that is what really grinds my gears.
