My father saw ball lightning. He described it as occurring near a small fence -- really a couple stakes and string with flags for visibility hanging off it. Said that the ball would hover as it jumped from post to post then fizzled out.

Ball lightning is one of those things that you'd expect to be easier to detect because of the increased use of cameras. Why isn't Youtube flooded with dozens of videos showing lightning balls? There are a few, but none of them are convincing. (One is clearly a drone being flown in a thunderstorm.) Most are fakumentaries. (3 seconds of shaky zoomed-in "proof" and 5 minutes of a so-called expert breathlessly talking about it.) How can ball lightning both have lots of people claiming to see it, but is infrequently caught on video?

My suspicion is people are encountering normal lightning discharges at close range and the "ball" is an illusion caused by how eyes work. If someone attempted to get ball lightning on camera they'd be disappointed to see the recording look nothing like how they remembered it.
