I don't know about the Most Improved, although it has improved and has probably been the most active along with CP and SFMM
SF GAdv.
at the end of the 80's the company really figured out what type of money maker the place could be, but before that it really only had 3 longer term coasters: Mine Train, Lightning Loops, and Rolling Thunder. Other than that they were on the Six Flags ride rotation program, hello Bobleds, Shockwave, Ultra Twister....Goodbye. Then in 1989 they open GASM and they change their way of dealing with the park. THey dissapoint everyone bye getting rid of Lightning Loops. but look what replaced it. Since then (yes I know Shockwave was in the 90;s). They add Batman, B & R Chiller, Medusa, Kingda Ka, Nitro, Skull Mountain, Medusa, hello Viper bye Viper, and now El Toro. It was a park in bad shape in the early nineties that was improved...fell on some hard times clientele and service wise during the Premier Parks run, but has great potential, a great coaster lineup, a great location, and it has the one thing that all other parks wish they had, but don't....Room for expansion.
