Buena Park--You can call this the other Orange County entertainment capital. Within a 20 minute drive from Disneyland in Anaheim, Buena Park offers its own brand of fun. From Knott's Berry Farm to Pirates Dinner Adventure, the thrills don't stop at a city that attracts several million guests each year to its theme park amusements and family entertainment.   Buena Park was built on simple things like chicken dinners and apple pie.  Many years ago Walter Knotts and his family had a restaurant in town that served delicious home cooking so popular, they began creating things to do while diners waited in line. Panning for gold was one of the first forms of entertainment offered. Paying homage to California's roots and rapid growth after the discovery of gold in the mid-1800's, as the Knotts family succeeded even more and accumulated wealth, they invested money back into the local economy by expanding their dinner entertainment to include Old West themed buildings and artifacts. Orange County, itself, was better known for orange groves, dairy cattle and farms. But it was also tied to the boom the Gold Rush created as local ranchers supplied many types of food to  Northern Californians. While nearby Walt Disney was imagining a fantasyland of rides to entertain families and kids at Disneyland, the other Walt was serving up a more historically-based attraction to educate and preserve a portion of American history for children and adults to understand and learn about. Thus grew Knotts Berry Farm theme park, funded by food and berries.   Knotts Berry Farm has one of the biggest outdoor wooden roller coasters in the United States, called Ghost Rider. It also features 165 rides, an Old West themed area where you can pan for gold, ride a stage coach and learn about the Old West. Then there's Camp Snoopy for the younger kids with easier rides, and Snoopy appearing for photos and fun.  Arcades, a parachute drop, Supreme Scream and Montezuma's Revenge make for a day of entertainment. Across the street is a replica of the historic Independence Hall with a Liberty Bell.    Medieval Times dinner show and Pirates Dinner Adventure are two other attractions just down the street from Knott's Berry Farm.  There's enough to keep you busy for a full day and several nights in Buena Park.   Adventure City, 1238 S.
