I just figured something out. The park went from wonderfully maintained (so my grandparents and their friends say) then, for a few years after the Nelson's took over, it turned crappier over the years. In the mid 70's, it was suggested they close the coaster because of the condition. It probably wasn't WG cyclone condition, but from what I've heard, it was bad. The nelsons kept it from there, and then in the 1990's things started getting better. In 2003/4 the nelsons pretty much went senile, and the park went down the drain.
