Haiti is a good reminder in why you make preparations. Granted, as mentioned, Haiti was disaster before the quake...what is shocking is that there is little to no communications, access to several areas is close to impossible and of course, water, food, medical assistance and sanitization are major factors and needs.
I've been reading "One Second After" about a very realistic post-EMP attack scenario and it's pretty scary to think of the chaos following a calamity where you don't have a clue if/when "help" will arrive and all things you take for granted are gone...communication, information, protection from the elements, refrigeration, heat, water, food, medication, etc. I cant imagine the horror that the Haitians are going through. One thing I can do is make sure my family can survive (outside of an immediate medical situation that requires serious assistance), for several days to weeks without assistance. Fortunately the kids are within walking distance (5-6 miles) from their schools and my wife is looking for a job in the local area. My job is about 20 miles from our home but it is back roads and theres a rail-road that parallels it. Having a Get-Home bag is critical for me and my wife if shes out of town.
