Aww man beach bend brings back some memory's. I have been a couple times. We stayed in an RV at there camp ground. Each time we went we would go to the park at least 2 days in a row. From what I remember most of the rides where portable. I think even the one roller coaster they had was somewhat portable, was on the pavement. The second time we went was much better and they had made a lot of progress, new rides, looked better. They where getting ready to start building new water park stuff.
It seamed to me at the times I had gone that it was more like fair. Since they had more portable rides then ones incorporated into the park. This was a while ago so I imagine its much better now. I wouldn't put it on any kind of level with most amusement parks but it was fun and a very "comfortable" park.
