Wow I've just stumbled on this neat image when I'm looking for a better "Riverside Bobs" blueprint for someone who is now strugging to replicate. This is perhaps because the keyword for an internet search engine "patent" is clearly something to do with coaster blueprints. I never thought that I really could see the figurative but feasible "4D Free Spin Larson Loop" attraction model.
Beyond imagination! Freakin' awesome!
