Always take a black jacket when you travel.

I have had the opportunity to travel quite a bit.  On my last trip, I brought a white sweater to wear over my shoulders in case I got cold.  The first time out, something went by a big mud puddle and splashed mud all over my white sweater.  I realized my mistake. When traveling, ALWAYS pack a black (dark) sweater or jacket.  Even in the hottest of summers, you will inevitably have a cool evening or be in a restaurant where the air conditioning is blowing right on you.  There is almost nothing more miserable than to be cold.  Always have a dark wrap with you to cover your arms.  If it gets dirty or you spill on it, nobody will be the wiser!
