I have never been to this park, so therefore I don't know exactly what the park is like outside of the pictures I have seen. Also, I don't know how much room SFEG has to expand, so this is all just an educated opinion of mine.
I believe this park should recieve a good sitdown, full-circuit mulitlooper; a floorless. It wouldn't have to be anything big, just a custom, well-rounded ride that delivers some decent g-forces and surprises.
Next, I think the park would benefit from another wooden coaster; a CCI out and back, something similar to Cheetah at Wild Adventures. Anything that delivers a good amount of airtime.
That would take care of major rollercoasters for the next 6 or 7 years. In the meanwhile they would focus on landscaping and customer satisfaction. That would keep park guests coming back for more, thus paying for their existing and upcoming rides and attractions.
Also focusing on the family would be nice. There is little or no competion for this park, and it would be nice if it was a place a family could go to have fun with their children.
This is a realistic example of what I think this park should get. It is important that this park knows what they are. SFEG has basically no competition, so why spend more than need be?
