Does anyone out there have an IPAD? Do they come with a built in GPS like most of the smart phones? If not, is there a GPS module that could be connected through a USB port? I just think the large display area would make the maps so much easier to use since you would not have to zoom up so far to see detail. Also does anyone out there know if you can "cache" maps from Google Earth? I am going to be elk hunting in Southern NM this fall. I will be camping up in the National Forrest way away from any cell phone signal. But I would like to take my laptop to be able to pull up Google Earth maps while in camp to plan the next days hunt. Is there a way to download maps of the area I will be hunting and store them in my computer so i can pull them up even though I don't have a data connection to my laptop? Any suggestions?
