Have you ever had a close call while exploring? Whether it be with sketchy people, bad trail conditions, or spoopy paranormal shit. Bonus points for squatch/goatman/urban legend encounters. I'll start

>Exploring abandoned textile mill
>Two separate facilities, one for processing/manufacturing, another for storage and shipping finished product
>Linked together by a skybridge-type structure about thirty feet in the air, spanning over a railroad line
>Explore manufacturing, neat equipment too look at, even paperwork left in old desks, cool mailroom
>Decide to cross over into shipping via the skybridge
>Wood flooring looks okay, to my eyes it looks like minor dry rot.
>hesitantly step out, nothing happens
>Reach out with my foot and test the areas in front of me before stepping
>no creaking or groaning when I put weight on it
>take another step
>foot goes straight through the floor
>panicmode.exe engaged
>Thankfully just my leg went through up to about my knee

Needless to say I decided to go around the outside of the building and use the bay doors instead of the bridge
