Spring's Herbicides

Ah, spring, the sweet smell of... herbicide. And next to the kids' playground no less. They applied this stuff all around my neighborhood last week. The smell was weird - an anti-smell really. Kind of burning, metallic. It's amazing how hard it is to avoid a truck filled with noxious green fluid in the springtime. In related news, the EPA is reviewing the safety of the chemical glyphosate in the popular pesticide Roundup. They've given themselves a 2015 deadline to make a decision. Glyphosate has become increasingly less effective over time. Is anyone really surprised by this?
