Spent last Saturday at the Belle Isle Aquarium. It was the longest continually-run freshwater aquarium until it was closed 6 years ago. Now, it's only open several times a year including the "moving of the koi". Twice a year, 50+ year old koi are moved from the aquarium's basement to the outdoor pond and then back.
Saturday my sister and I joined dozens of others in this fabulous event. As another volunteer said, the only way to save Detroit is one volunteer at a time.
