Mysterious Trash Can

This falls under the category "on the way to Clinton Hill!" For those of you who switch trains at Hoyt-Schermerhorn every night like myself, you may have noticed a peculiar garbage can near the back end of the platform. For a few weeks, it was surrounded by yellow caution tape, and most recently it sits covered in a giant black plastic garbage bag. Of course, most people ignore the covering and toss their trash on top.

WTF is up with this trash can?? Why has it been covered up for so long?? If there's something wrong with it, why can't it be removed and replaced? What in the world could be inside? Yes, my first thought was along the lines of corpse, but that would be pretty stinky by now.

Seriously, this annoys me.
