Some years ago people used yellow pages or phone books to find address and then they used map to find the direction. Well, it is totally unpractical way to find address and so yesterday because today with internet technology you can find the address that you need and direction in the same time just by doing several clicks.
There are a lot of sites that is offering you this service and you will be surprised that some of those sites are offering their service for free. For example is you are really new in Dallas, TX, you know nothing about this city but you need to go to a supermarket to purchase some of your daily needs. What you need to do is just clicking the related local directory for example is Austin, TX if you are looking for information about supermarket in Austin or Houston, TX for supermarket in Houston. After that, immediately you will be provided with the list of supermarket in those local areas complete with its address and map direction if any.
So, there is no point of you to bring map everywhere you go because some sites are able to be browsed rightly from your cell phone.
