"A useless rope..."
"To the Club House!"
*Batman melody*

Well, we soon discovered that we didn't have any "rope", but we had a spool of twine. We walked over to the parking garage and wondered how we could make this rope useless, but still cool. We went to the stair well and decided that it would be cool to make a big ol' web. Round and round we spooled our web, meticulously sewing our snare. When we were done, we let a line dangle to the ground, just to pique a passerby's attention. Then when they look up, BAM, too late, they are already in the spider's snare.

I would also be afraid of putting anything in that parking meter... might just loose a hand to the beast that made that trap...
