Q. Can you suggest locations where I'm most likely to see the Northern Lights? How about tours?
Karen Deneroff, Oakton
A. The colored light show known as the Aurora Borealis or Northern Lights can be seen hovering at least 60 miles above the Earth's surface on an almost nightly basis in some parts of the world. Generally, head for north of 60 degrees latitude.
To see the lights at their best, you need dark, clear nights, and parts of Alaska, Canada and Scandinavia are the places to go. Sadly, scientists have recently noted that Alaska may lose its Northern Lights in the next 50 years, as the north magnetic pole (a key part of the whole lights thing) is speedily heading away from North America toward Siberia. But for now, you can head to Fairbanks, Alaska.
Lights "can be seen here an average of 243 days out of the year," said Karen Lundquist, public relations manager at the Fairbanks Convention and Visitors Bureau. "It's definitely a very surreal experience. I've seen people cry and cheer." Have patience and more than a day (you never know when cloud cover will show up). Tours generally head for an established site around 10 p.m., where folks hang out until 2 or 3 a.m. For a vetted list of companies offering tours and acommodations, check the What to Do category under both "aurora viewing" and "snow sports and winter activities" (800-327-5774, http:/

I'll be traveling to Peru (Lima, Cuzco, Machu Picchu) on a tour. I've heard conflicting tales regarding preventative shots before traveling. What shots do I need?
Judy Herman, Fort Lauderdale, Fla.
The reason you've heard conflicting tales is that it not only depends on where you're traveling but who you are: Personal physical history is an integral part of the equation where prescriptions are concerned. The key to figuring out the madness is distinguishing between required vs. recommended, and with your itinerary, there are no required immunizations, according to the U.S. Centers for Disease Control and Prevention (CDC).
But you're not puncture-free yet. The CDC recommends that all adults and children regardless of travel plans be up to date on what are considered routine shots, and that includes tetanus-diphtheria and measles-mumps-rubella (see http:/
As your itinerary is limited to Lima, Cuzco and Machu Picchu, according to the CDC you don't need the yellow fever vaccine. Erik Mederos, an assistant at PromPeru (866-661-7378, http:/
With your itinerary, malarial prophylaxis aren't needed; elsewhere in the country they are. And even if it's not a requirement for entry, other vaccines that can be recommended for travel to tropical South America include hepatitis A and typhoid. (In addition to Peru, tropical South America includes Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Paraguay, Suriname and Venezuela.)
At any rate, there's no substitute for talking with your doctor or visiting a travel medicine clinic at least four to six weeks before departure to figure out the best course of vaccinations. In addition to country-by-country vaccination recommendations, the CDC (877-394-8747, http:/
