This is one nice topic but why are people pointing out the negatives to this?
I'm sorry but a video could just not possibly prove what can and can't go wrong with this idea. Seeing how that is their expectations, how many times has shit stuffed up in the past? it's a bad idea, scrap it. it'll not go down well, i'd not allow them to touch my street with even a shred of the stuff but thats just me. :/.
