I recently took a trip to Los Angeles, and as I approached the northern part of San Fernando Valley on rte 5 I began to see lots of chem trail residues..as I got even closer there was a stench in the air which felt very toxic. I was going to the west part of san fernando valley and simply turned my car around and headed north with my air vent closed. I took another more northern route to my destination, and the air was fairly good, so I was greatly relieved to avoid bad air. I checked the web site for chemtrails, and there had been reports which indicated that LA had been sprayed heavily for at least 5 days..I believe it. Keep all car air vents closed is the one rule that I follow now. CA
