Go figure!

I was driving home from Camden Market yesterday and I went uder a railway bridge. On the bridge was sprayed "STOP GLOBAL WARMING". Interesting. Apart from the fact that I question the term "Global Warming" and its implicit meaning that we're all going to hell on a handcart because we drive and eat and screw, I was surpised by the intelligence that thought vandalising public property was justified; especially becayse spray paint uses butane -- a gas which has ten times the "greenhouse effect" of carbon dioxide. What a blow for sanity.
