I once walked into a golden orb weaver's web. It was across a trail, just above my eyeline but low enough to catch my forehead. I basically fell backward (from being clotheslined) and proceeded to panic jump back to my feet, spinning in circles brushing at my clothes while my hiking buddies helpfully told me it was on my back still (it never left the tree). Their webs are super strong and very beautiful (from a considerate distance!)
