For me, packing is easy. Number of days gone = number of dress shirts and dress slacks. Throw in a pair of jeans and something casual and wear casual while travelling. Razor, travel toothbrush, travel toothpaste, deodorant, pills, 2 belts, casual shoes, dress shoes, underwear for number of days plus 2, dark socks for number of days, 3 pair white socks., If it is gonna be cold, wear a coat and pack a dressy sport coat and a casual one. If not, wear the casual sportcoat and just pack the dress one. Load up pockets, laptop bag with equipment and pills, and travel humidor in the morning and pack the car up the night before of everything else.
