Outside of Agnostic.com what kind of groups do you find open minded individuals? I've been on the road for the past 20 years and am finally taking a break from the constant travel. I have enjoyed groups, such as slack line groups (kind of like walking a tight wire) but closer to the ground and some of the flow groups, juggling, hula hooping, etc.
None really, can't say I identify with the group mentality, but to each his/her own though.
I'm in kink groups and gaming (board/role playing) groups. I've also been involved in a maker space when I've lived near them.
