I could likely name a whole bunch, but really only two stick out.
Six Flags over Texas: Being a self-proclaimed "SF Brat", I'd like to go to the park where it all started. I almost made it there once back in 1989, but there was a Hurricane down in those parts so we scrapped the trip. I'll get there one day.
Silverwood: I'm not a fan of traditional parks, but Tremors looks like the most phenomenal coaster I have seen in a while. I mean, a tunnel through the gift shop? Wonderful! Alas, I aint making any trips to IDAHO anytime soon so it shall stay on the "wish-list".
