The Society for Creative Anachronism (SCA) is an inclusive community pursuing research and re-creation of pre-seventeenth century skills, arts, combat and culture. The lives of participants are enriched as we gain knowledge of history through activities, demonstrations, and events. (From the SCA home page.)
The SCA is a world-wide organization divided into Kingdoms, and Kingdoms into smaller regions. Glymm Mere is a Barony of the Kingdom of An Tir, which roughly encompasses the US and Canadian region mundanely known as the Pacific Northwest. Glymm Mere is located in Western Washington, including the counties Thurston, Grays Harbor and part of Mason.
