Cedar Point's Top Thrill Dragster used to have a similar procedure, but I don't think they ever rechecked the train for somebody pulling down a bar, and that policy is gone now. Maybe SFMM could attach placards to the trains saying not to pull down the lap bars? Or, maybe next time it is down for maintenance, maybe a system could be installed that locks the lap bars up until a ride op comes around and pulls them down.
"Official" Cedar Fair fanboy!
Favorite Steel: Maverick|Favorite Wood: El Toro, Goliath is close behind|Favorite non-prefab/RMC woodie: Hard to say. Probably Shivering Timbers or Georgia Cyclone
Favorite Flats (in no particular order) - MoA NU Brain Surge, Chance Chaos, Flying Scooters, drop towers
I take a stand against unnecessary neutering of rides. Restore Revolution, Blue Streak, Dorney Thunderhawk, Raging Bull, etc...
