Meal Checklist
On a camping trip in the past I noticed that we were missing an ingredient needed for a meal and then we noticed that we didn't have another for another meal the next day. I used MS Excel when we returned to make a check list with check boxes that has some of our favorite camp meals.
All we need to do is select the meals that we want to eat in advance and add them to the list. We print the list and make sure we have all the ingredients needed. If not we can use the list to speed up shopping. Lists can be done for some of your gear, clothing or anything else that you might want to take along with you.
The best part of using excel, for example, is that you can save the lists for future camping trips and have to only make minor adjustments.
