Cobwebs

Real ones.

A bit like something out of a Hammer Horror... where there's always someone who decides to go in somewhere dark... and it'll be full of cobwebs... and you want to tell them... "Don't go in there! It's dark and if you do, something will get you!!!"... and they go in anyway... and... well, I'm sure you know the rest, if like me, you watched all the old Hammer Horrors in the 70's!

Luckily for me this was taken in broad daylight with bright patches of intermittent sunshine... which was such a relief!
