I think I just witnessed the most amazing spectacle mother nature has put on show. Nearly two hours of thunder that echoed through the valleys for well over 20 seconds each time, sounding like explosion after explosion. And fork lightning spanning the entire horizon and my field of vision. The lightning was more frequent than the thunder, as if someone flicked on a light switch and illuminated the entire sky above me in colours of violet. So bright that I had after images in my eyes of fork lightning that split into at least 6 parts. This was no ordinary storm, I've seen many and for me, this was a once in a lifetime experience.
