You see those guys in the woods all of the time, they can get pretty big....now imagine you are riding a bike in the woods on a bike trail and you fly right smack into one of these damn webs and wind up with that huge bastard right on your face...it happened to me as a kid, AAAAHHHH!!! It didn't bite me but I was emotionally scarred for a LOOONG time afterwards.
Brrrr, I get the shivers just thinking about it.
The one I'm talking about actually looked like this (about half the size though) this is also a banana spider...
