Ruffryder, where did you get your information? You are accurate on a few things, except the name of the coaster was not Psyclone. Actually, the coaster was called the "Whoopee", and it was built and operated at Neptune Beach. I used to teach an Alameda history class at Crab Cove Visitor Center in Alameda when I worked for the East Bay Regional Parks District, which runs the visitor center. I am an Alameda native. The area where the park used to stand was filled with bath houses and gardens. The amusement park opened in 1917, and closed in 1939 due to the effects of the Great Depression. Too bad too, because if it had stayed open one more year, the coming war would've brought a lot of business to the park. There were large salt water swimming pools that used to filter in water from the bay. They also had a boxing ring where they would hold prize fights. Croll's building near the McDonalds used to house a gym and training facility where a few famous fighters from the era used to train, including Max Baer. If you go to the visitor center, there are great photos of the area, including the coaster. If you ask one of the student aides or one of the naturalists, they might even let you see some of the photos they have stored in the back. Also, the Alameda Museum has some photos of the area, but not as many as Crab Cove. Peace. :)
