I've been in N.Y. where the air is a thick brownish fog with a distinct taste similar to boiled mud water. I've also sat on the 405 out in L.A. as it curves down to Santa Monica in a yellow haze and scorching o-zone free sun rays. I've never seen anything, anywhere similar in all my travels (though I'm sure China, & India may be worse). Every time I've been in Europe, Canada, Mexico, etc... the air is always much cleaner. continue
