I'm waiting to see how this turns out. If the march is small Monsanto will view it as vindication of their policies. If it's large enough it will turn some heads in Washington and we may get a fairer break in the courts and laws. If the turnout is somewhere in the middle it will pretty much be ignored in the media.
Looks as though the march was a success. Estimates I've read say that over 2 million participated in 52 countries. Now we'll see if the government is listening.
The account of the march that I saw on TV, portrayed Monsanto as a tolerant and benevolent benefactor of plentiful nutritious food: "We respect people's right to speak their mind...." Of course, that was from Missouri, the home of Monsanto. grrrr
