He's been on the job guarding the entrance of the Science Museum of Minnesota for 21-years. Now it's time for him to take some time off and do some sightseeing. Iggy, the 40-foot Iron Iguana, is being hoisted onto a flatbed truck next Wednesday. He's going to stop by the Gillette Children's Hospital, take a drive down the Nicollet Mall in Minneapolis , and eventually settle into his new home at the new science museum overlooking the Mississippi river in St. Paul. Nick Swearer is Iggy's creator. He started building the giant sculpture when he was just 15 years old. I asked Swearer where the inspiration for Iggy came from.
