Here in Durham, we're planning to take advantage of the usual last-minute filing of tax returns at the Post Office on the night of April 17 -- and the usual local news coverage of this event -- to meet people as they are mailing their returns and hand them this leaflet:

You could easily do something similar in your community. The above website has individual breakdowns tailored to each state, so you could just download their form and head to the photocopier.
This is the kind of action that can work with just one person. Of course, if you have enough to cover several sites, you'll spread the word that much more quickly.
