I rode HSTC for the first time at PPP a couple weeks ago. It was CRAZY! The chain lift extends into the entire station and it speeds up as the train arrives to propel it forward. It's very loud, and very fun! I was surprised when I found out there is a minimum height requirement of 48", 42" with an adult. Seeing pictures of it, it didn't look that crazy. But seeing it in person and then riding it, wow!
