Our block's haul -- there were another 4-5 bags on the other corner. We had 13 people helping at one point or another, although not all at once, and we picked up the e-mail addresses of three or four other people who weren't able to participate this time but would like to do it again. We didn't put out "move your car" signs but were able to shovel out most of the gutters in spite of the cars.
And everyone is psyched to do it again. This is great!
