Terrypin - I owe you one. Until this very second I never realized you could just drag a .gpx file into Google Earth and have a path created. I've always been converting to kmz first.
But the drag/drop thing works! Thank You!!!
The color appears to be fixed, but to change the color of the path, once it opens in Google Earth right click and choose "Properties". Then select the "Style, Color" tab and make any changes you want.
Does anybody know how to keep the path visible while zoomed out?
