The Camelot Society will host its annual Chili Cook-Off & Auction fund-raiser from 5-8 p.m. Nov. 13 at the Northshore Senior Center (10201 E. Riverside Drive, Bothell). Admission is $8/person, $15/couple.

The Bothell-based nonprofit agency serving developmentally disabled adults is celebrating its 40th anniversary this year. Founded in Margo Thornley’s vision, the original site was her family home, which was modified to accommodate eight children. The subsequent expansion started with the construction of the Camelot home in the Greenwood area of Seattle. An architect was brought on board to design that building. During that time, the state of Washington passed the Education for All Bill, and the children being served were able to attend special-education classes.

Soon afterward, Thornley was able to obtain a Department of Housing and Urban Development (HUD) grant for four more homes. The restrictions from HUD on how much of the grant funds could be spent on the site acquisition caused Camelot Society to end up with the sites in Woodenville and Duvall. More residences have been added over the years, among which the original five still remain. The two homes in Woodinville exclusively house adults with Prader-Willi Syndrome (PWS) and are the longest operating residential facilities for people with PWS in the world.
