Very nice flight shots Paul.
@Greg, Area #4 is good habitat, but you'll have a hard time getting low, since the area is raised up. For a good low angle, you can try getting out into the beach #1, 2 or 3 _early_ in the morning. You have some nice ponds/puddles in the sand, and just park yourself in the sand and let them come to you. You'll likely only have less than 1hr of shooting, since this is the beach for campers/day-use.
