I can only imagine what that must have sounded like....
Okay...referring to your post #30...the line you are using to measure needs to be perpendicular to the street lane lines which are parallel to the street edges. Using those as your guide may help you get a straighter line... :) It will shorten the width, but be more accurate. Earlier I saw a time lapsed video of the protest. They used a three and a half hour window to shoot it in, but the streets were not full for the entire time. I believe the link was on Free Republic on another thread, I will look and see if I can find it.
