If you're going on Vacation and you are counting on your gps for driving directions, or your cellphone gps for reliable driving directions, then you may as well just drive into the Grand Canyon or over Niagara falls.
Your cell phone will loose signal, the battery will croak, and/or your charger will quit working. Then you will inevitably be lost in an unsafe location, with either wild animals or wild gang members
trying to kill, rob, rape, eat, shoot, bludgeon, or jack you. That's not a memorable dream vacation.
So you need to print driving directions and Maps using MapQuest before you go anywhere new.
Did you know MapQuest not only has the BEST Driving Directions & Maps, but also
walking directions.
These two below obviously didn't. They were looking for the stairway to heaven. Good thing it wasn't windy or they'd have been airborne.
