Appeal Democrat Park

Colusa Casino Stadium (formerly known as Appeal-Democrat Park, Bryant Field and later as All Seasons RV Stadium) is a stadium in Marysville, California, USA. Its name reflects a sponsorship deal with Colusa Casino and Resort. The stadium is primarily used for baseball and is the home field of the Marysville Gold Sox, formerly named the Yuba-Sutter Gold Sox, of the Horizon Air Summer Series, a collegiate woodbat league. The ballpark has a capacity of 4,000 people. Located on the corner of 14th & B Streets, the stadium has the look and feel of an old-time ballpark with its brickwork trim, sunken dugouts, and outfield wall adorned with billboards.

The stadium served as host for half of William Jessup University's 2015 home baseball schedule.
