So now I'm a kooky envirowhacko because I oppose the spraying of an entire city (every month for 10 years)?
Yes. Apparently you have no idea how many times San Francisco has been sprayed in the past. I lived in the bay area for 15 years, and I saw it many times.
And yes, San Francisco is smack dab in the middle of one of the largest, most productive agricultural areas in the world. They spray the entire region, or they may as well not spray at all.
