Are the hazer and light 'fire effects' not working at the moment? They seemed to get a good reaction from the general public when I was riding.
Just not sure if you had that, and thought it was unconvincing and not sufficient of a finale, or if that was missing from your experience.
(In the dark section at the end there are jets of haze with lights behind to simulate fire)
The tunnel at the end was just a dark tunnel last weekend.
it definitely needed something like what you describe to round off the ride.
