I've noticed in several journals, as well as posts from new people in the past few days, the question of staying low carb while traveling. There are vacations, which present one set of problems (easier to control what you eat, more temptations) as well as business trips where you may have to eat at luncheons where you can't control the food, or the schedule is tight -- you definitely can't cook.

What do people who are frequent travelers and long time LCers do about traveling? How do you handle staying LC?
