The cyclist was further away - plus the gator was occupied with the snake.
When I was a kid gators were afraid of people because gators were killed if they got close. Then snowbirds started coming to Florida and feeding them - and the crybaby liberals worried about the poor gators’ feelings and lives. Now there’s too many gators and they’re not afraid of us anymore. That said, if you stay out of the Everglades and don’t swim in infested lakes, you’ll be fine.
I used to camp in the Everglades. I remember being out early in the morning in a canoe near Florida Bay, and there were gators everywhere - just looking at me, waiting for me to flip my canoe.
