Don’t Rely on Your GPS

The other day, a friend was coming to my house so we could go hiking. I gave her the address, but warned her that some GPS units and phones like to take people on a dirt access road behind my house and told her to follow my directions. She ended up on the dirt road behind my house with her GPS unit chiming, “You have arrived.”


I’m morbidly fascinated with dumb GPS mistakes. Lately there have been an influx of deaths (many in Death Valley, of course) of people blindly following their GPS units or Siri's voice onto dangerous dirt roads, into lakes and mud holes and nearly off the sides of cliffs. GPS is a wonderful tool, but just like any tool (that can break) don’t rely solely on it if you are traveling in unfamiliar locations.

If you have a medical question, you usually don’t go with one source or one piece of advice. You ask several medical experts, do some of your own research and maybe read some books or articles. Do the same when you are traveling. If you have to get to a specific location, use several sources and compare how the information is given to you.

1. Google Maps and Google Earth:

Before you leave on your trip, use Google Maps to see the various routes that you can take to your destination. Another problem with relying on a GPS is that you blindly follow one route (usually the shortest, but not always the best) without knowing what else is around. 

I’ve met people who have become so reliant on their GPS that they don’t even know how to read a map anymore. They don’t know which way is north, south, east and west and they don’t recognize the difference between a secondary road and topographic line.

Google Maps at least allows you get a feeling for directions, time, surrounding terrain and various obstacles. It shows you nearby towns, services and other attractions. The 3D options of Google Earth shows road types, canyons, mountains and tall buildings that don’t translate well to paper or GPS.

2. Paper Maps: 

Since some remote areas are not always mapped by GPS, always take a paper map of your desired location. Some of the best maps are the Rand McNally Road Atlas, Benchmarks Maps & Atlases and specific trail and park maps offered by REI. I’m a paper map junkie and love to pore over them before, during and after a trip. I love to see where we are going and what we will see and experience on the way to and from our destination. A GPS can’t give you that holistic satisfaction.

The best thing about paper? You can write all over it. Mark your location, any special notes or issues you have noticed on Google Maps.

3. Ask the locals: 

No matter if you are going to New York City or Oatmeal, Texas, there will be a local who knows more about the area than you do. Ask for directions and about attractions from cops, coffee shop owners, grocery clerks, librarians, RV hosts and adventurous teens. You might make a new friend and won’t have to contend with Siri’s annoying voice for miles of unending dirt roads.



GPS or Map?

The latest Apple Maps flaw which sent drivers along the Fairbanks International Airport taxiway and across a runway might have people questioning their GPS units. We've had our own issues with GPS units when visitors to our home get directed to take a rugged, dirt country road behind our house when there is a perfectly (and well mapped) paved road in front of the house.


So should you trust GPS units and map apps or is the good old paper map the way to go? When we are traveling with our teardrop trailer, when we need to be even more vigilant, we like to use both.

GPS units are useful for finding the quickest route or an alternate route in case of traffic jams or road construction. They are also very useful in more urban areas when looking for specific streets, stores, restaurants and laundry facilities. However, a GPS unit is NOT a map. Don't blindly rely on just a GPS when foraying into unknown territory. A GPS only gives you a very narrow view of the entire location, you need a paper map to see the entire area and plan your trip according to what roads you want to go down and what you might want to see along the way.

Map = big picture
GPS = fine details

One of my favorite blogs, the Long Long Honeymoon, covers this concept nicely in a video. In addition, an article by the Boston Globe confirms that primarily using GPS units to get around affects our brain's ability to assemble a mental picture of where we've been.
