I really enjoy skeptic conferences. There's something wonderful about being surrounded with other people who want to see the world for what it really is, and who actively want to get others to as well.
Not all of these meetings are big, like Randi's Amazing Meeting. Some are cozier, intimate, but they are just as innovative and inspiring. Skepticamp is a subset of the BarCamps, meetings where people meet and share ideas on a given topic. Skepticamps are held all over the world, but the next one will be in Castle Rock Colorado on March 22, in just a few days.
People who attend generally (but are not required to) give a short presentation, and the idea is to share ways of spreading critical thinking to others. I would hesitate to call it skeptical evangelism, but you get the idea. Randi's organization has donated food and swag, so that's an added incentive. If you're in the Castle Rock area you really should go. And you should join the list of Denver Skeptics, too!
