Minneapolis, Minn.: Is there a definitive way of finding out beforehand what purchases from duty free shops overseas are and are not allowed to be brought on board an aircraft? On a return trip from Portugal last year, I was not allowed to bring on board candy that I wished to purchase at the duty free in Lisbon. Luckily, when the cashier saw from my boarding pass that I was traveling on Continental, he told me it wouldn't be allowed. Same for perfumes, wine, and other products. When I asked the Continental agent at check in if there were any restrictions, she said there weren't. I seem to have the same dilemma with trying to figure out what can and cannot go through security in terms of makeup items. Thanks.

Peter E. Tarlow: We are chatting about this at the Las Vegas tourism security conference. If it is a direct flight, you should not have any problems. The issue becomes if after you arrive in the U.S., you have a connecting flight, then the liquid rules apply. Always declare all items to U.S. Customs; they are much nicer to people who tell the truth.

Staunton, Va.: Going to Cabo San Lucas on October 13th. I take about 7 prescriptions that come in a 90-day supply bottle. Is it ok to take them in a weekly pill box or do I have to bring tnem in the large bottles? Thank you, Two Seniors

Peter E. Tarlow: Go to your pharmacist and get perscriptions in smaller bottles or carry a note from your doctor on his medical stationary explaining what you are taking with you. Use the Latin or technical name for the medication.

Philadelphia, Pa.: Hi, Peter. I wanted to plan walking the trail system in France with a female friend (I'm also a woman.) We were looking at the easier hikes in the Loire or Burgundy areas. But, we were discouraged by others who said that it wasn't safe. Our husbands, who don't speak French and have no interest in a walking trip, aren't dying to go. What's you opinion about the safety issue for two women alone? Do you think it's real or just others imposing their own insecurities on the situation? Thank you for considering this question.

Peter E. Tarlow: In the end we are in God's hands, but I would oppose my wife making this trip. I cannot guarantee that you will be safe and better safe than sorry.

Peter E. Tarlow: Sexual assault, robbery, and kidnapping.
