Preparation Pt.2 "The List"

I have learned that taking time to create a "List of necessities" for a trip, when I am not planning one is a great asset to planning. The lists that I have are unique to the kind of trip I am taking. They have been helpful in eliminating "oh I forgot the toilet paper" realizations after you've just hiked 25 miles into the wilderness, or the "whoops! only one pair of underwear for the week" realizations....and if you Haven't had one of those realizations before....you will! Unless you utilize the list.
Make these lists when you have time to sit down and consider everything that you will need for the journey. Not in the few days preceding your departure, where you will feel rushed to finish the list and start packing. You can make a basic list of items before you even have a specific trip planned. The specifics should be a part of a separate list unique for the destination.
