Yesterday I tweeted a link to a news story about how the Zippin Pippin at Bay Beach Amusement Park is 75% structurally finished - and then I happened across these photos. It looks like even more than that is now done!
There's just a small section of the turnaround yet to go up, then the structure will be complete. As seen in the photos they are also starting to work on the station, queue entrance, and more. There's going to be plenty of time to test the coaster before opening next year.
