That's when I see them. On occasion, I will walk right into a web and having your face covered in spider web is one of the most disconcerting experiences ever.
Usually I end up flailing my arms and smacking myself all over my head in case there is a spider in my hair. I can only imagine what other hikers that can see me from a distance must be thinking.
"Hey, check out that dude over there, he's having a nervous breakdown...he just SNAPPED!"
