A few days ago, “Geographic Travels with Catholicgauze” had a great post about the size of the crowd at Jon Stewart’s “Rally to Restore Sanity“.
It seems that conservatives have been passing around an image that shows Glenn Beck’s rally with a much larger crowd, but the images were taken from slightly different viewpoints to make thing look different than they actually were. He uses some great images (with overhead maps) to show that the rallies were roughly the same size.
You’ll want to read his full post to see how he put it all together, but it makes sense.
The reason I bring this up is because GeoEye just released a beautiful high-res image of the crowd that day. While it doesn’t definitively answer the question of which rally was larger (and I’d rather avoid the politics of determining that), it certainly shows quite a huge crowd at Stewart’s rally:
To view it in Google Earth, I’ve taken the high-res version of the image and created an image overlay for it. Download that file and you can zoom down pretty close to check it out.
