I have thought about starting a local meet up with anyone who was interested, perhaps a weekly or monthly meet at a library or free gathering place, actually the park sounds good it being outside and natural... that could be a topic - fluorescent lighting vs sunshine... Craigslist could be a good free way to advertise and then go word of mouth.
Anyway I would think that 99% of people would not be very receptive if it's anything like the people I talk to, between the thousand yard stare at the mention of enzymes, nutritional importance, mercury etc., and the weird facial contours upon telling someone to do a Liver Flush
instead of paying a surgeon to hack their organs out... most people have been brainwashed but heck if you got that free minded 1% that's still a lot of people... You could do some Youtube videos, maybe even start a channel and get paid for it - I'd probably subscribe.
Still, there is something about meeting in person, more powerful, healthier I think, better than conversing through videos or forums. Of course drawbacks are limited membership and convenience, and some health matters no one is going to mention face to face with others.
Count me in if ou are local.
