In this new double-sided map from London-based map-makers Herb Lester, you'll find an overview and potted history of 30 of the more interesting North American cults. From 'end of the world' healthy eating advocates The Ant Hill Kids to hierarchical farming commune types The Zendik Farm Arts Foundation, you'll find a great deal to ponder over (and as plenty are still going concerns - perhaps join!).
The 400x690mm litho-printed guide would be an excellent companion across the States, you could even send one of the 'Help I've Joined a cult' postcards included within the pack.
