Wow, such a complete description!
Think I fit in the Pure Enjoyment Guy category, but some other I can relate to also.Think I often walk around with a somewhat borred look on my face, untill the drugs kick in, that is. (Nothing to be proud of, I know, but it's just so true.)
I saw an Eso Goan guy last weekend at Rhakti, (a few actually) but this one definatly fits into this category, he was walking around in a cowboy-like outfit with feathers in his cowboy hat, with a beard, a somehow freaky, but huge smile on his face trampeling around with a few Himalayan Healing Insence sticks, trying to spread his positive energy, waving it in everyones face....
Couldn't hold myself from lauging, what a strange character.
