thats interesting, have you been to sedona yourself? if so how was your experience?Sedona's awfully large and the entire areas affected by vortexes. Being in Sedona for even a day changes a person. Seems to get happy, in a religious way. Personality also changes.* For just finding vortexes on a filed before you, in mid Summer looks for bugs like midges, which are mosquito sized, to congregate over vortexes. This is your simplest way to find them.
