Generally - the publicity is word of mouth. They don't spend any money to print flyers because wherever it is possible, no money is involved - nor should it be. This is the first year many cities have done the ROS - I think its an awesome and inspiring event - the news stations and such should be notified, community event calendars can be used, and I know they wont stop ANYone from spreading the word! Anybody can call a tip line though, the organizer may already have called, we can call again!
