Some time ago, I was marginally involved in the Green's efforts to put Nader on the MD ballot, and called a meeting in Columbia, MD - a dreadful, utterly sterile suburb between Baltimore and DC. The meeting did not materialize because the flyer informing about the meeting had the directions wrong - and navigating through Maryland's suburban wasteland is quite a challenge. I love the Greens dearly, but that anecdoce speaks volumes about their organizing potential.
