What should I bring into California's Great America?

Bring sunscreen, a hat, and sunglasses as it tends to get sunny at California's Great America, but a jacket or sweater is a good idea too for evenings and weather changes in the Bay Area especially in late fall and winter. The park suggests wearing comfortable shoes and cotton clothing that dries fast. All backpacks are purses will be scanned, and chairs, glass, speakers and all weapons are prohibited.
