When you get ready for a camp.
what do you keep on hand instant oatmeal, tea, picknic stuff, small containers of unopened Catchup, packets of mayo & sugar, box of surving ware, D.O. inserts, Ice in the freezer, Charcal in a can, extra camp fuel, wood, 3 sets of BBQ tools (we keep mis placing them).
These are things we keep handy
Then it off to the store. We start thinking camping 3 wks ahead watching sales, we start looking for minitures at stores like personal goods, we might go to the meat counter or we might wait until we are driving then stop off and pick up fresher meat then.
We use 3 or more coolers. one with a block of ice at the bottom (usually come back with half still there, back in the freezer it goes.) (some use Dry ice). We try not to open it keeping it closed most of the time. One for picnicing and daily use. one for beverages. We have a container that holds foods in dry packages like teabags, and we use dog food containers for pans and cook ware (they have side doors and can be stacked so you can gain enterance without moving the box above.)

What do you do. or how have you simplified this process
