I was watching Airtime Thrills new video about this and wondered what members here thought for Ohio (His was Steel Vengeance, Millennium, Maverick and Orion).

For me, it is:

Steel Vengeance

Top Thrill Dragster

Orion

The Beast

What say you? 

I would agree with the above, however, I would swap out Orion for Millennium Force and possibly Dragster for something representative of the old Geagua Lake (Six Flags Worlds of Adventure) - Big Dipper, perhaps? I never went when it was open, so I don't know that their most memorable coaster would be.

So, again, here are my picks:

Steel Vengeance

Millennium Force

The Beast

Big Dipper [or insert something memorable from Geagua Lake here]/Top Thrill Dragster

Racer needs to be there for mostly re-starting the coaster building spree after it died off in the Great Depression and WWII.  

Also defunct coasters from CI like Shooting Star and/or Wildcat.  

EDIT: My list- Racer, Beast, Big Dipper from GL, Shooting Star, and Magnum. 

I haven’t ridden much coasters at cp but I can already tell you that SteVe is in the Mount Rushmore of Ohio.

My list: SteVe, top thrill dragster, Maverick, Orion

I like aggressive rides and millennium force is fun, but I don’t find it very intense.

For historical significance, I think the Ohio Mount Rushmore would be Racer, The Beast, Magnum XL 200 and Millennium Force. 

I'll be (hopefully) riding SteVe in a couple days for the first time and if it lives up the hype, it would certainly go on here. The video that OP is referring to, from Airtime Thrills, is really looking at standout coasters by todays standards, so in that vein my picks are:

-Diamondback

-Millennium Force

-Mystic Timbers

-Orion

Was never a huge fan of Maverick but I've only ridden it a few times so maybe I'll change my mind. TTD is great fun but its not complete enough of a ride. And I won't say much about Magnum except that it just doesn't make my list.

If we could include specific scenarios, then a night ride or a rain ride on The Beast would be on there.

Orion, Flight of Fear, Millennium Force, Maverick

They only put old dead guys on Rushmore so shouldn’t it only be RIP coasters?

The defunct Mount Rushmore is also interesting. Some of those old CP coasters I don't know, but for me I think it would be:

Son of Beast

Big Dipper

Vortex

X-Flight/Firehawk

None of the defunct CP coasters in my lifetime anyway would make the list. 

"Mt. Rushmore" is so overused, the meaning often gets lost.  The historical significance should mean more than biggest, fastest, newest or most popular.

My OH coasters of significance:

Racer

Beast

Magnum

Millennium Force
