In this toic you put what you would get if you had 1 billion dollars
What I would Do:
Buy SFGAM and move it to a place it can expand
I would move all the rides and coasters to the new site except AE and IW.
I would add a 4D coaster, large out and back woodie, rocket coaster, floorless, water coaster, screamin swing, sky swat, a stand up larger than RR, a hyper similar to S:ROS (SFNE) and several more rides. I would also add attractions to make it a multi day resort. With the money left, I would put it in the bank to save for college nd my future.
