The Oahu events were among the 215 taking place across the country organized in conjunction with 350.org.
The Honolulu Star-Advertiser covered the Kailua event with a photo and thorough article covering 60 square inches. See the article (may need account to view).
For more photos including those from actions all over the country (and even in other countries), see the Draw the Line set on 350.org's Flickr site.
