I think if I put a LW meetup on, well, Meetup, I might draw some people out of the woodwork. In the description, I'd give a brief explanation of the word "rationalist" (as "Boise Rationalists" will probably catch more eyes than "Boise LessWrong Meetup"). I'd also include links to this site, HPMOR, and Khaneman's books, and a blurb about eventual goals. What's your opinion on that strategy? I know that when I moved to the area, I browsed Meetup for interesting groups and attended several. Talking to others, I've learned that they did the same. If I'd seen "Boise Rationalists," I would have been interested.

There's a group that's only a seven-hour drive from my location, so I could make that a few times a year.

I hadn't thought of the EA angle! That might be more palatable to some newcomers.
