Matt Drudge created a bit of a stir a couple of years ago with this Tweet:
I’ve been a Drudge Report reader for over 20 years and have often said a prayer of thanks for Matt’s consistent dedication to exposing corruption. That Tweet, though, that has been stuck in my head ever since I saw it. “Have an exit plan…”
As a prepper, I suppose I have a number of exit plans. Some are quite thorough and have become reality with marked up maps and a few bug out bags. However, Matt’s warning has recently caused me to think twice about my preparedness.…Read More...

I have done a lot of research on Faraday Cages and feel like I am finally beginning to understand them. A Faraday Cage is designed to protect electronics from EMP (electromagnetic pulse) that can be created by high altitude nuclear explosions or solar storms. See previous posts on EMP. Some simple examples of Faraday cages are shown below.
- A booster bag (shopping bag lined with aluminum foil) acts as a Faraday cage. It is often used by shoplifters to steal RFID-tagged (radio-frequency identification) items.
- The cooking chamber of a microwave oven is a Faraday cage, made to contain the RF (radio-frequency) signals of the cavity magnetron which cooks the food.
