Get in touch with the Hopedance community in SLO via their newspaper/journal of the same name. Bob Banner is the publisher, and his e-mail is Hopedance@aol.com The website is
http://www.hopedance.org They are tireless in promotion of peace, permaculture, ecology ... They have regular film nights in SLO, and those would be a good place to meet likeminded folks.
You might check out the activities at the Unitarian Universalist Church in SLO to see if they have a peace committee oriented toward community activism. A couple of years ago I spoke with the nascent committee at the Santa Barbara UU, but ultimately they decided that many people were already working frantically in so many areas (we had not yet invaded Iraq) that what they really needed was one place to become personally peaceful. Everywhere I've ever been involved in anything to do with social justice the UUs have been well-represented. Ditto peace activism, so there are likely to be people who can point you in the right direction.
Groups periodically demonstrate outside Vandenburg AFB, but personally I won't go there because I don't want to confront the military on their own turf, especially when conditions are terribly tense as they are now. Yes, it's a public highway -- but if you get arrested it's a federal rap, and besides, if the 1960s taught us nothing else, it's that weapons sometimes discharge.
Nonetheless, as you probably are already aware, Vandenburg is the beating heart and electronic nerve center of America's satellite spy system, so it's a big deal.
I met Rosemary from Lompoc during the Santa Barbara peace marches and actions leading up to the invasion of Iraq; as a result I went to some of the Lompoc meetings and still get notices of them. Sorry I don't have anything recent, but try e-mailing her at rholmes@eap.ucop.edu -- tell her you asked at DU and Sheila suggested she might have the information you need.
The Santa Barbara chapter of Veterans for Peace was the only chapter between San Francisco and Los Angeles until one of our members started a Ventura county chapter. I just checked my last copy of the roster (I'm an associate, or non-vet, member) to see if there was a name from Lompoc on it, but didn't see anyone. Our website is
http://www.vfpsb.org/index.html and I think there's direct contact links to people who might know more.
Hope this helps.
