I just found a new thing out about this. Click on teh map; it;s a link that shows county-by-county responses. In most counties, about 10 people were asked, which is not a true estimate of soda-pop. Plus my county, hartford county, was not on the list, but it had a color on the map, so this thing is totally innaccurate.
EDIT: click on your state, and it shows the responses by county. In some states, 10 people per county were aksed, but in otehrs it was 1000. still inaccurate though.
