Got any gum, chum?

Non-stick chewing gum - whatever next? Mind you, it's the bane of the street-cleaner's life. My local town recently repaved its central area, and within days the new paving was dotted with grey-white splodges - which are still there and multiplying. If this helps eradicate the problem then I'm all for it, although perhaps more emphasis should be put on stopping people dropping the stuff in the first place.
