The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid.

Join us as we get together to get together to help those in need at this CMG Gives Back event! We have a great little community of Movie Group friends so rather than see a movie this time, we’ll help “create a better world” by helping serve those in need. Here are complete details and our plan for this event: FAITH MISSION – GRANT KITCHEN: The Faith Mission kitchen and dining room serves residents 3 meals a day, every day of the year. For this event, our group will help prepare food, serve meals, assist residents in the dining room, wash dishes, and clean surfaces. PLAN: We will be preparing / serving / cleaning for BRUNCH from 10:30am to 12:30pm and have space for a total of 7 volunteers. Please arrive at 10:20am and wear closed-toe shoes and long pants. LOCATION: Faith Mission – Grant Kitchen is located at 245 N. Grant Ave. Enter the kitchen at Dock 1 (in the back of the building), indicated in the attached map. On-site parking in the adjacent lot and street parking is available in the surrounding area. Below are some links / attachments with additional info/details: IMPORTANT REMINDER: Our group will be providing all of the volunteers on this day so a firm RSVP count is essential. Please only sign up if you are certain you’ll be able to attend. If something unavoidable comes up, please try to update your RSVP no later than one week prior to the event. With few exceptions, no shows or cancelations within 1 week of the event will not be eligible for future CMG Gives Back events. I appreciate your understanding as we try to ensure the agencies have the volunteers needed to provide the essential services they provide to the vulnerable population they serve. Our Partner Agency for this event is Lutheran Social Services! A huge THANK YOU to all of YOU for volunteering at this (and any of our previous) CMG Gives Back events! Should be a good/fun/meaningful time together, Dan
