Outdoors? No. Too little coverage from trees where i lived
I contemplated it though, back when I was Wiccan, just to experience 'being skyclad' and 'one with nature'.
My personal beliefs are..I dunno. It's hard to define. I cringe at the words 'religion' and 'worship'. I consider them more a lifestyle, I guess. Encompassing religion and philosophy up to the point where they merge.
The actual lessons I learn on that path I very much apply to others, and vice versa. What I learn from others influences how I practise my spirituality.
