I think you're right on there Dave.I vividly remember a guy up in the rear lounge ;drink in one hand,coins in the other.He managed to load the one armed bandit then would wobble across the room until the next roll brought him back to the machine.Smilin the whole time.After about an hour of this,I was religated to watching the latrine wall while holding on to the wisely placed hand rails.I remember the steel vibrating faster as I guess the prop was cavitating on the downslopes.My Ford Capri rental to Oliver's Mount was the better of the trips,hands down!
