Chloe, he's worried that people will be giving out wrong information. You know with all the hotels moving around all the time and such. After all, Banana Beach has moved from 1.2 to 1.41 miles from the town square. People that have stayed there when it was located at 1.2 miles might confuse those that end up staying there now that it is at 1.41 miles.
I'm sure he's equally worried that someone might report that there is seagrass to be found here and there, but maybe the specific seagrass has moved or been raked up. Or report that they've seen nurse sharks at Cypress Gardens when others have only seen them at Amigos Wreck. Or possibly, he's worried that someone might tell another to put their left foot in the water, when it is their right foot that should be guiding them.
You know that sort of thing. The things that change all the time, that's what he's worried about.
A fish and a bird can fall in love, but where will they build their nest?
