National Park(ing) Day is an opportunity to celebrate parks in cities and promote the need for more parks by creating temporary public parks in public parking spaces. National Park(ing) Day is Friday, September 19, 2008.

San Francisco art collective REBAR first created "PARK(ing)" in 2005 to re-imagine the potential of the metered parking space. In 2006, in collaboration with TPL [The Trust for Public Land], REBAR founded "PARK(ing) Day": a global exploration of the creative potential of streets.

Liberals! Progressives! This must be addressed to you. Who else, since it started in San Francisco and they are promoting "public" parks.

Sounds like fun.
