I find that the need to Bug In / Shelter in Place / Hunker Down is the primary survival M.O. before any bugging out takes place. Good to test both, but remembering that the most important thing in your BOB is actually between your ears makes testing that piece of gear paramount. If you get good at bugging in and can maintain focus and discipline of the mind, then you can branch out and try other forms of survival. The reality is that you will likely be trapped in a home, office, store, mall, sports arena or airport if there is a sudden SHTF moment.
Think about earth quakes and stuff - no warning and getting to your vehicle is 2nd to sustaining life where you are now. Hurricanes yuo get a little better warning on, but if you elect to stay and the Hurricane elects to remove half of your house, well - then you are in quite the pickle. Same with wild fires and roving hoards of zombies or what ever threat you may face.
Get good where you are right now - then get good somewhere else. Then after that - get good in a third and fourth place.
