Re: [Slasher Flick prep] tell me of the Camarilla
During my (brief) time with the Camarilla, I would characterize the organization as having been a swinger's club for gamers, replete with copious alcohol and drug abuse, unplanned pregnancy, and regular trips to the health clinic. This was, of course, before White Wolf reasserted firm control over the organization (which is, itself, a story that gives valuable insight into the collective mindset of the Camarilla at the time).
The current Camarilla is, I gather, 100% more safe and sane. Although I'm no longer a particpating member (and haven't been since about 2002), I have some freinds who are and who assure me that the organization's days as a safe haven for social deviants and budding criminals is completely over. White Wolf, apparently, has some extensive checks and balances in place which prevent abuse of power and the endorsement or facilitation of illegal or otherwise dangerous activities.
As for LARPS in remote locations? Yes, I'm sure that some of them take place there. In Topeka, we held bi-weekly sessions at an abandoned retirement home for the better part of two years (the caretaker obtained permission from the owners for us to use the property). After that, the games primarily moved around from one apartment complex to another. Prior to that (and before I was a member), games were held in city parks. Oh, and we often held troupe games (i.e., non-official games) at Lake Shawnee's picnic cabins after dark.
With regard to organization, on site at a typical (Chapter) game there is usually one Chapter Storyteller and two or three assistant Storytellers (possibly more, as needed). A Domain Storyteller may occasionally drop in. Here's a good, brief, look at organization
If you're going to base a Slasher Flick game around the Camarilla, if I were you, I'd set it about ten years in the past, at the height of the organization's bacchanal days. There is plenty
of motivation for a psycho killer there.
