Letter Re: Smart Phone Maps

Mr. Rawles,
My wife and I don’t have a lot of money and we didn’t want to pay to have a smart phone so we chose to have basic phones.  A friend recently upgraded to a new carrier and gave me his Android X with a 16GB SD card in it for $25.  I was happy cause we could use to entertain the kids on road trips or what have you.  But I recently found out that I can download Offline maps onto the SD card.  I’m sure you’ve seen an SD card for these phones.  Its about the size of your fingernail.  The phones battery wouldn’t keep a charge that well, but I bought a brand new battery online off amazon for $5 shipped to my door.   I’ve downloaded a map for every state that I would travel, or walk through if TEOTWAWKI happens.  But even more impressed I am finding out that I can get Topographic maps downloaded offline onto my SD card as well.  This could become very helpful in case of a long hike, to be able to navigate terrain. 
 
Even if I had to pay $100 for this, it would be a good investment.  With a portable solar charger the battery would only need to charge for a few hours and the battery unless used continuously will last for several days.  I’m going to get an extra phone and keep it in an ammo can to protect it and get the biggest card 32gb that will fit in it and prep it for WTSHTF.  I don’t get a lot of time to read your blog anymore due to the bad economy and the necessary increase of hours in order to make up the loss of income.  But I hope that you and your readers find this information helpful.  I have informed my family and will help as many people as I can to get this squared away as an aid. 
 
We can also put medical information and color schematics on the phone.  Almost anything and everything that books can provide can be produced to a format for smart phones.  This is really exciting for me. Thank you, – Justin C.
