Didn't realize it was so tall until standing next to it, then understand what over 600ft tall really looks like!
Wife didn't think we'd go to the top, but we did. Kids 14, 10, and 5 had fun, the 10 year old a little leery of the ride at first, but once up top, she liked it.
Would recommend checking out if driving through the St. Louis area.
