I will have my passport card in my wallet, but if an ICE fu>ckhead stops me, I am still not complying. I am a US citizen, so the pig does not have jurisdiction over me. But the "Don't Tread on me" crowd thinks I should comply.
The passport card is for traveling. Now unto the Real ID. Yeah, I am a procrastinator. I haven't had the need to fly, but that may change.
