My Garmin is not getting any sat signal. I figured it had gone chesticles-up, and decided to head to a Walmart to replace it. Of course, without a GPS, I couldn't find the closest one. So, I knew where a Best Buy was, so I stopped in to buy another GPS unit, which would get me to Walmart to get a refund. At Best Buy, the sales guy said GPS wasn't working, and sure enough, none of his units were. As I was talking to the sales guy, another customer carrying the same exact GPS unit I have walked up and said his wasn't working, and bought another one. Is there a GPS outage I don't know about? Some other SHTF stuff going on I should know about? Solar flares? I checked Google news and couldn't find anything.
