First interlocking corkscrews?

I want to say Medusa at
SFGAdv. but...

AC?, RB?, MF?, DD?, PR? Who can keep track of it all?

I believe Kumba was the first to have interlocking corkscrews.

Actually I think it was Drachen Fire @ BGW.

Well, drachen fires corkscrews were interlocked in a different way...

In RCT Terms...

Medusa, Kumba, ect.. have interlocked corkscrews, where both are taken the same way (left corkscrew, wrap around, left corkscrew).

Drachen Fire, on the other hand, had a left corkscrew, then wraparound, and then a right corkscrew. It looked weird, but they were technically interlocked.

BTW I think the first "real" set was kumba.

How much more floorless can they get?
