On Friday, Nov. 20, nearly 400 people — about half of whom camped overnight — showed up at Chicago’s Cricket Hill at Montrose and Lake Michigan to brave the season’s first snowfall at the Out in the Open Sleep Out.

Out in the Open is the first project of Pride Action Tank, a new, results-driven group that addresses challenges facing individuals and groups within LGBTQ communities through a collaborative process of inquiry, advocacy and action. This event was created to increase awareness and raise funds to support Chicago’s most vulnerable youth — those who are homeless or experiencing housing instability.

The event has so far raised over $40,000 from over 700 donors for over 18 Chicago-area charities that work on issues relating to LGBT youth homelessness. Donations will continue to be accepted through Dec. 31, 2015! Take a peek at 10 tweets that capture the community’s dedication to supporting the estimated 22,000 young adults who are impacted by homelessness at #SleepOutCHI.
