Thank you so much for the kind words and for taking the time to read my post. I know this was a fairly long one but I tried to summarize everything as best as I could to avoid having some important details lost on the way :)
I get headaches in pretty much any place known for magnetism so that, perhaps, it's normal. But all the sounds you can hear there and the mystery that can be felt at, any step, makes things unique for sure.
Either way, I'd love to visit this place at least one more, but with a guide. Just to get a bit more background than what I felt on my own :)
