Dunno, I will take this one with a grain of salt, then see what happens.. This may be one of those incidents where kids are getting worked up over something silly.. Of course they need to check and pay attention, but it sure sounds suspicious to me.. kind of like the man in the black coat that never materializes..
This is exactly what I think (and what SK thinks too, apparently!) No adults have seen the clown, only kids. They are likely trying to scare each other. "I just saw a creepy clown!" "Oh yeah, well, I saw one with candy and he tried to get me to come into the woods!"
Hope so, anyway!
