I would absolutely, positively, definately 100% say BLUE STREAK at Cedar Point. 
 
Everyone praises that coaster for its nastalgic value... for its ACE Coaster classic out & back, but to me... 
 
 It Sucked!  
 
I will back it up with a lil' explanation. 
It appears all simple. You go up the hill and then start going down and up blah blah blah, turn around up & down and blah blah blah. You'd think that with such a simple layout, how could that coaster be rough?! 
 
It was ROUGH!! It was jerky. I'd much rather ride Mean Streak 5 more times than Blue Streak. Going up or down, it just jerked too much and was a head banger!  
 
I wanted to like it, but I was really glad when the coaster was over with!!! 
 
(ps: I hope they re-tracked that coaster this year, otherwise... it's gonna get 2 less riders this year)
