This should link to the blog “Listening to Katrina.” One of the best “preparing” type blogs I have read. Not applicable to every scenario… but full of good stuff. (and that’s not just my opinion..I have seen it referred to often).
Here in NZ where we have earthquakes.. you perhaps get NO warning.. and no chance to bug out. You just have to be prepared to survive. In my location it is likely all the roads would be blocked by rockfalls/ landslides. We could not get to nearby towns , hospitals etc.
