Take a month and use it to plan before doing anything.

First you need to know what you're planning for...then

You have to figure out how to afford "all that stuff".

Begin by closely examining your financial situation. Look at every dime you spend. Make a bare bones budget and stick to it. Cut out all frivilous spending...no eating out...no beer and pizza etc. Have a yard sale. Pick up extra work on the side or get a part time "night" job and use the funds it generates for your preps.

Second. Do a Threat Assessment for your area. Look at all the things that will probably happen or could happen. This will include probable natural or manmade disasters, severe weather etc. What are the ramifications of each? How would these events affect you? Once you know what to prepare for you can actually begin.

Make an evacuation plan...where to go, how to get there and when to go.

Ok, startin from scratch...

Build your ammo supply to 1000 rounds min. for the rifle...250 rounds for the pistol.

Get a basic load bearing set up. If you shop around, you can find decent surplus for reasonable prices. Use the H-back harness, add a USGI canteen, mag pouchs and a butt pack.

Put together a 72 hour bug out bag in a backpack.

Buy a case of MRE's then start buying a little extra canned food every chance you get. Begin with a minimum 2 week supply of food then build up your stock to 30-60-90 days etc.

Get a scanner and a shortwave radio.
