Welcome! This is mainly a "local" forum for American Civil War cavalry reenactors in the Pacific Northwest. It will have dates of events and trainings as well as any items of interest.
I believe the Cleveland Bay horse in Canby might be 16.1 at most that's what they say he was as a 6 year old in Wales. They have some photos on the internet.
You'll have to do a search on Cleveland Bay in Oregon.
