I mentioned before that I was excited about being able to put satellite images on my GPS receiver because Niki and I have gotten lost at the nearby state park on a few occasions (and a couple of times at night). It can be a bit stressful.
So, I finally sat down and got organized about putting satellite image files on my GPS receiver. I automated the generation of the coordinate files, automated entry of placemarks in Google Earth, and had a pretty quick system for getting the images generated. Got them all done and on the GPS this afternoon, went to the park with Niki, and...she wouldn't leave the parking lot.
