Wow! A bunch of new environmentalists! I think experiences like yours is what makes more of them (us).
Actually tallyho8 I'm sorry to see that happened to you.
Long ago we had a big spray related controversy up in Humboldt County (where the back-to-the-earth types went when the 60's were over). A hippie lady, pregnant and carrying a small child and identifiable by her traditional long granny dress was sprayed mercilessly, drenched with Roundup or something, on a bridge where she couldn't escape. This was done by a yahoo working for the highway department. It was in the papers for a long time since it emphasized the huge difference between the 'spray won't hurt you' farm boys with their sense of humor, and her desire to live a life free of synthetic chemicals.
I doubt she was very political before that, but this may have been the origin of one of those tree huggers you see in the news.
