I'm a skeptic, but I remember in the late 90s I saw something on T.V. that looked very similar. Back then they were calling them arrows. You couldn't see them with the naked eye but when you slowed the video down they sort of looked like arrows. They moved very fast and changed directions unbelievably quick. I've never heard anything more about these so called arrows.

Anyone remember or see anything like that before?

Peace.

p.s.
I enjoy watching Finding Bigfoot too, but I don't believe in it.
