I love maps and I wanted an easy way to display our route across America. I thought it would be cool for the girls (and everyone else) to look back at the places we've been. So I wrote a small little application for my phone using appery.io that saves my current location and displays it on a map.
So when we get to a cool place, let's say Savannah, I can enter my coordinates and short description about where we are at and save it to the database. People can then view the Map page and follow our journey. Quick, simple and cool.
