Disclaimer: This is my personal experience and in no way reflects an endorsement of nor preaching about said group.
Locally (Portland, OR) I attended a UU service out of curiosity and my partner at the time's desire. I was pleasantly suprised when the "church service" started out with a Tibetan prayer bowl and the "main talk" was about Fred Rogers (Mr Rogers) and what a cool cat he was. It was a non-pushy, non-christiany, non-churchy (though in a church) church experience. After the initial visit (I rode my motorcycle to the place and walked in wearing tshirt, jeans and facial piercings) I attended a few more times and took a UU 101 type class. Interesting group, they described themselves as "athiests with children". Basically, not interested in religion so much as they wanted to gather with like-minded people and provide a social environment for their children. Still not my gig and I can't really be arsed to get up early on a Sunday to sit and listen to anyone (rather be riding).
The reason that I mention this on this particular thread is partly in response to some of Black Swan's experiences religion wise. The main reason though is that the local UU has a Pagan group associated with it. So within a technically Christian religion you have a subgroup of defenite pagans, athiests and mixture of eastern religions. It was a nice way to get aquainted with several different religious basics in one place. I no longer livein the area where this group was located, but may still make the trip back there for some of their pagan gatherings for the educational opportunities it would offer.
