I bought a data cable for my Garmin 76cx the other day. I downloaded my waypoints in Google Earth. It also allowed me to download my tracks and points from the GPS. Its mindboggling to go back and retrace my steps on the lake. One place where I was fighting the wind trying to get back on a brush pile for a while...looked like someone had been doodling in that spot. I expect a lot of you guys already knew Google Earth had that capability, I didn't and I was impressed.
