During my life, I’ve packed for several different sorts of travel.
There’s the quick trip for business or to attend a conference. Pay close attention to the wardrobe — you want to make a favorable impression.
The vacation. Road trip or airline travel? Companions? Save room for souvenirs! Consider the weather and how much time you intend to spend out of doors.
Some trips are planned far in advance. Others come up at short notice. All of them require a few invisible items. Patience. Flexibility. Sense of humor.
