Update: So, I originally posted this when San Andreas came out, but now NASA and the USGS are arguing over whether the 99% chance prediction of a major quake in the next 5 years (NASA) is fear mongering vs. the much more reasonable 85% chance (USGS).
Are you going to see San Andreas? Are you ready for the big one? Turn a (clean) trash can into an emergency water tank. Good to have on hand for earthquake prep or in case of other emergencies where you might lose access to clean water.
I am not a prepper.
