I'm on enough lists already...
Serve in the Armed Forces? Government has your prints on file, and a full set of your service record.
Contribute to a political party or candidate? Hell, everybody has your name!
Driver's License? You are in more databases than you can count!
Passport? Hunting/fishing license? Birth records? Transcripts? Associations/Clubs? Subscriptions? Financial records? Tax returns? The list is endless...
And don't forget how much can get mined and sifted in the electronic frontier, especially by the NSA!
Sometimes I figure "what's one more?"...they know where I am already!
