I would hate to see the Speedway go simply because when we took our grandkids a couple of years ago, the only ride my granddaughter specifically wanted to ride was the cars. She loved them. That being said, she was four and probably has already outgrown it.
I'm not thrilled (pun intended) with a 60mph launch coaster. I hate R&RC. I live less than 30min away from Six Flags Over Texas, and I saw a wonderful theme park turn into an unthemed thrill mess in just a few years. I'd hate to see that trend repeated.
