We launch over a Orwood and run up tp Pittsburg. The Sheriff and the USCG set up course boundries to keep spectators of the course. The course runs around a large island right off of the marina. Any where on the water at the edge of the course is as close as you can get. From shore, your own your own. Good air show, and food after the race, have fun, look out for the Sheriffs BUI testing, saw it going on two weeks ago at the Walnut Grove intersection.
