What We've Learned

· Warm up to your seatmate, since you never know when you'll need a friend.

Trains and Subways

· On subways, stand near the door for a quick getaway.

· Check Amtrak's Web site, http://www.amtrak.com/ , for information on possible last-minute security-related delays.

· Never ignore a bag left in the aisle or at a seat. Get out and inform a security official immediately.

· Pick cars at the far ends of the train, since they will be less crowded (everyone heads for the center cars).

Road Trips

· Embrace the humble highway. Flying hassles may lead you to load up the station wagon, even for long-haul trips. You can have more fun than you think with books on tape, motel pools and roadside diners.

· Keep your gas tank filled.

· EZ Pass, EZ Pass, EZ Pass. When there's a Code Orange backup at the Holland Tunnel, nothing feels better than leapfrogging along the fast (or at least faster) lane.

At Your Destination

· Once on the ground, keep alternate plans on hand for getting around. Ask your hotel's front desk how to get to restaurants or other venues by public transportation.

· Find the nearest pharmacy to your hotel so you can buy any toiletries you left home because of the liquid ban.

· Tune in to the television, radio station or newspaper at your destination. They can alert you to any local security concerns.

· At museums, arenas or ballparks with metal detectors, find the entrance the farthest from the subway or parking garage. People tend to head for the first entrance they find, and it's always the most crowded.

· When touring museums and churches, carry only the essentials, and bring only a small bag so you won't have to check your valuables.

And Finally . . .

· Be more observant, but never scared -- and never stay home for too long.
