Have a Safe Halloween

For Friday
Costume Carnival
Halloween falls on a Friday this year, which means the streets will be filled with more nighttime traffic, party-goers, and general mayhem than normal.
If you are hesitant to send your children out into the possible unscrupulous activity, consider taking them to the Seattle Children's Museum for its 3rd Annual Costume Carnival.
The festivities will include a "Not-So-Scary Haunted Mountain," a Mad Scientist Lab, and scavenger hunts.
Costume Carnival, Fri, Oct 31, 4–7pm, Seattle Children's Art Museum, 305 Harrison St, Free
For Saturday
Southeast Seattle Climate Justice ForumThere's nothing like a community coming together to define, instruct, and educate itself on important issues, especially when the consequences of these issues extend beyond the community itself.
The Got Green Young Leaders in the Green Movement and the Seattle Office of Sustainability and Environment (say that five times fast) team up to discuss the impacts of climate change on the SE Seattle community and action steps that can be taken on the ground floor. Spanish translation available.
Southeast Seattle Climate Justice Forum, Sat, Nov 1, 2–5pm, Southside Commons, 3518 S Edmunds St, Free
For Sunday
Washington Water Trails Association Film Screening
The WWTA Fall Paddling Seminar attracts a niche group: river paddling enthusiasts. No one is going to knock paddlers for their hobby, but not everyone shares their passion enough to attend a two day seminar.
That being said, the issues being covered in the seminar's film screening—the impact of the Northern Gateway Pipeline on British Columbia's Great Bear Rainforest—is a cause we can all get behind. Paddlers attending the Fall Paddling Seminar get in for free. The rest of us landlubbers must pay $15.
Film Screening Hosted by Blazing Paddles, Sun, Nov 2, 6–8pm, The 2100 Building, 2100 24th Ave S, $15
