I have been hearing a number of folks in other places talking about asteroids coming our way because Jupiter is slightly out of orbit.
A number of "peppers" are talking about this.
Whether or not it is true, there are a number of places in the alternative news that follow this. There is a book written years ago by Larry Niven called "Lucifer's Hammer" that discusses a comet heading toward earth.
The reason I mention all this.... If someone acts quickly, a pepper's guide to surviving a disaster could make a few bucks. (I think I remember a book by Tess Penington) Not enough time to check right now.
