I saw another puker yesterday (not me). Also some kid in the station really seemed to be having difficulties, probably with dehydration or heat exhaustion.
Yeah, the heat must be keeping people away. I went yesterday around lunch time. I rode Fury 10 times (2 from the front row), and the last 3 rides were without getting out of my seat (row 7). They were cool with it, as long as nobody was waiting for your row. I asked before I did it and the one op said it was fine as long I didn't do it too many times in a row. I think he didn't want to clean up more puke. I can't say I blame him.
There is probably something to the theory that short lines might cause more pukers. And the heat must make it worse. But, there were plenty of other pukings on days with much longer lines, and cooler temps, so who knows. I personally think that the marketing of the "biggest, fastest, newest" just really did the trick. And so lots of 'first-time-folks' are going to Carowinds that otherwise would not have. And some of the coaster-noobs are finding out that they are susceptible to motion sickness.
After Fury, I had lunch (best lunch at Carowinds yet

). Then I rode Intimidator 3 times (all from the back seat). And I headed back home to the Air Conditioning.
That was an awesome 2 hours at the park.
