If I ever got into urban exploring, I'm positive this is how I'd get caught.
There would be something unique in the dwelling. All the authorities would need to do is see who is Googling for a Black, 8" diameter ABS pipe with 5" X 1/2" treaded rods. Or something similar like that.
Either that or I'd get caught in the building, obliviously examining something. Trying to discover it's backstory sheerly by force of will. ;-)
This is why I never take anything. It's generally damp, wet and soggy anyway!
