I feel like before I take a trip I start mentally packing at least two weeks in advance. I start thinking about what I’m going to be doing and what I envision that looking like. I’ll make mental notes, start putting certain things to the side here & there. About 10 days out I’ll start checking the weather. Then there’s lots and lots of mental notes until the tons-of-lists start. Surely it should be no problem physically packing a few hours before it’s time to leave.
