Travis - if you upgrade to an Android phone another option instead of Lattitude is My Maps. Although I sort of stopped doing it later in my hike, I did start a "tracking map" where I would try to make a GPS way marker and add a photo to upload. This kept my Mom happy. For all the "cut the cord" stuff people are saying, its important to keep Mom happy and not worried all the time. If you go to my journal, there is a link at the bottom to the map I was using.
