Marilyn Megenity's Mercury Cafe is a Colorado institution, beloved both inside and outside of this state. It's also a no-brainer for a left-leaning catalogue of American collectives, co-ops, eco-conscious and alternative businesses, think tanks, coffee houses, favorite leftist anthems and restaurants for locavores, but we were still happy to see that The Nation Guide to the Nation mentions Denver's long-lived, free-thinking hippie outpost not once, but twice. Lauded for its rooftop windmills, organic fare and alternative politics, this Mercury is still rising.
