Ran into people from this institution at the Taylor reptile expo more than once, and finally got around to checking them out. Made a day of it, and went to Ann Arbor. It's called Great Lakes Zoological Society. It's kind of what I had eventually hoped to do. They take in rescued reptiles, and made a reptile zoo, and a very nice one, too. Took a few pictures - the enclosures were spacious, and they had a lot of monitors, including a blue tree monitor who was very inquisitive, and came right up the window to investigate the humans staring in his window. And of course, pics!
