Well, I did respond promptly -- I filled it out the day it arrived, and put it back into the mail the very next day. Two weeks later, I received a second identical form, again telling me to fill in the blanks and return it promptly. Had I known that people in the Augusta area have never received their forms, I would have been glad to pass it on to someone.
Needless to say, I saw no reason to be counted twice, so my second form was put through my shredder! What an inefficient government we're witnessing.
