15 police and sheriff's agencies are in Santa Barbara this week, at the Earl Warren Showgrounds for specialized mounted patrol training.
The agencies are working day and night in various settings.
Santa Barbara County was able to coordinate the training for statewide agencies, which have normally gone to Riverside County for the program.
As part of the drill, scenarios include crowd-control, noise and helicopter coordination will simulate what could take place on the ground in a variety of situations and give the horses a realistic example of what they might encounter with big crowds.
