This is the swim route from g-map pedometer. It is 31.8 miles, but is straigh lines. I didn't swim straigh much as the boat gps had 34.1 miles. I will try and manipulate this to show different points i spoke about in my story. The 16 mile point is Gulfport Harbor. The Penthouse apartment pier is between the 23 and 24 mile points. The Pass harbor is at the 27 mile point. You can click and drag the map to see different points. To zoom in you need to type in gulfport, ms or another town and then change the zoom level on the right.
enjoy
