jbensman, I looked at the My Trails map and the trails listed for Hawaii are perfectly accurate. Thanks very much for the map, it will come in handy. Unfortunately you don't have a topo or road map for Hawaii. The topo map posted by -Oz- is very nice with the topo lines and main roads, but mountain peaks, waterfalls, secondary and unpaved roads are all misplaced, some by .3 or .4 miles. The garmin topo 100k map has these with better accuracy, though it's not as detailed on the topo lines and is missing a small amount of these data that -Oz-'s map has. I was just wondering if this was on his radar to fix?
