Really enjoying your report and pics. If you ever get tired of the beach try the cliffs. We get very little harassment up there. You can always visit the beach and leave when things get to much.
I get insect bites and my wife doesn't. I think the scripts she takes keep the little buggers off her. I apply an insect repellent in the late afternoon wherever I am. Sand fleas are everywhere down there. Not just on the beach. I got ate up on a deck 10 feet off the ground one night and could not believe it. No problem since I spray every afternoon and into the night.
