One interesting note from a SAR post got me thinking -- They suggest that when prepping for a night/evening search that you also remember that you may be in the field the next day - so bring a cool tee and your sunglasses, too.

I've learned that when you are packing, you pack for the local and current conditions; if its dry at home, you often forget your rain gear; if its raining at home you might forget sunscreen and shorts.

This is why I like packing lists.
