I went back to this highrise the other night. I'd been meaning to for a while, because the penthouses look finished, and I figured the total absence of security measures could not last forever.

My old POE was blocked with new fencing. But, to my delight and amazement, one of the sections of perimeter fencing (on busy Kingsway) was sitting ajar. So I just strolled in like I worked there, feeling lucky and blessed.

I climbed 45 storeys without much dilly-dallying, admired the views from the skeletal penthouse apartments' balconies, and climbed back down, perhaps forty-five minutes to an hour after going in.

The fence had been closed again. I was trapped inside! I felt unlucky and cursed, and very bewildered.

That fencing is heavier than it looks. I finally managed to rip one up off its peg, but then couldn't get it back in place from the outside. I did my best and casually skedaddled.

Had an employee without keys entered the site briefly? Had a thief, or a fellow explorer, been there? But if they took the trouble to reconnect the fence after leaving, why hadn't they bothered to do so while inside? Had a security patrol come by and finally noticed a gap that had been in the fence all evening? Mysterious.
