Here is where you'll find the first answers to your questions and inquires. As Chatelaines to the Barony they have loaner garb (clothing you can wear to events) for you to wear to an even if you are short on time.

Hadassah bas Yossi is the Chatelaine of Dun Or and would love to talk with you if you are interested in the SCA.
The Chatelaines (officer who helps newcomers find their way.) are the officers charged to help all newcomers who come to the SCA to connect with the local Barony in their Kingdom. In this case you are at the Barony of Dun Or (Antelope Valley, CA) in the Kingdom of Caid, see the map page, of the SCA.
