Attend and OpenStreetMap speaking engagement or mapping event in your town. Or organize a mapping event for your town.
The Software Freedom Day Mapping Fiesta was last weekend and here is a summary of the results.
Elmira, Ontario (pop. 11988) - one new OSMer had to put his own town on the map. He started the map of Elmira on his own, then headed to KW to join the team there for socializing. He even went out and mapped more on Sunday. Excellent start, Bob!
Kitchener Waterloo, Ontario (pop. 560,000 combined) - Five teams and individuals, including some first-timers, joined in mapping various parts of K-W. There is talk of another party before the snow flies.
