Yes, most of Florida is within 50’ of sea level, although there are some minor heights (345’ is the highest) in the Panhandle up toward the Georgia line.
I’m imagining a crowd of people shoving around at the edge of a cliff and feeling queasy.
I’ve developed a trace of fear of heights with age, but only while driving a four-wheel vehicle, oddly. I can still snow ski, mountain bike, dirt bike, or hike some real sketchy trails, often (in the case of hiking or two-wheel vehicles) while traversing a steep canyon wall with a mountain stream WAY DOWN THERE.
