Very Anticlimatic

For the past two years I have big bothered by the fact that there are weird dome structures in the middle of lake Michigan. Here's the thing. No one in the city (at least that I asked) seem to have any clue what they were. I will admit no one really seem to care either, but for some reason I was fixated on needed to know what they were. Until today not fixated enough to figure out what they were. What they are however is a water crib, i.e. how we get our drinking water in the city. As you can tell this is very anticlimactic. That is way more boring than anything I would have thought up in my head. Ugh I guess I'll have to find something else to be fixated on.
