Can we blame Thorpe (or say, any park) if a ride is truly borked? If they're waiting for a part from Utah then that's a problem slightly beyond their reach for Rush...
Slammer is gone, there's no point crying over it's non-existence anymore...
I wouldn't be surprised if Rumba was being closed at dusk (it wasn't before if I recall) since the incident at Drayton, like yeah I enjoy putting the boot into Thorpe a fair amount of time, but when there are valid(ish) reasons behind ride closures, then more fool those who moan and still visit the park in these times...
