Well Dave, to be totally honest, I am pretty new at rei over all. I have never done a full on thousand letter mass mailing or yellowletters or anything like that. I mail out my own preforeclosure letters and will get a few calls from that. Reason I like door knocking is that apparently I come off as a nice, respectable, trust-worthy young guy to most people lol and so I am able to make a personal connection with them.
Not to mention we live in the U.S.A., dont get me wrong I love America, I have sworn to serve and protect it, but not everyone here is, how do you say...... smart? Ha and so lot of people that get a letter, no matter how well it explains the process, just will not understand it, think its a scam, throw it away or not read it because it is cutting into their American Idol time.
Then again, door knocking can get pretty expensive when you are driving all over town, half the people dont answer their door, the other half is at work and the third half thinks you are trying to do a home invasion lol.
