With the GPS capability of many smart-phones, are the days of the dedicated GPS unit over. As long as one can get a cell-phone signal, Google maps of the area can be downloaded and cached beforehand. If a cell-phone signal cannot be received, the smart-phones, with an app, will display accurate longitude and latitude for use with a map. Any thoughts for or against?
When you're chewing on life's gristle
Don't grumble, give a whistle
And this'll help things turn out for the best. And always look on the bright side of life.
