If your traveling by air this Christmas season... don't wrap any gifts before you travel. TSA is very likely to un-wrap all your packages, even the ones in your luggage. Best to wait till you arrive at your destination before you wrap those gifts.
Oh, and you already know not to pack anything valuable in your suitcase right? Things like cameras, electronics, cash and jewelry have a way of vanishing during the time you check your luggage till the time you get to baggage claim.
