My my. It's always strange to pass by this stretch of St. Clair for me. I spent a few years as a teen frequenting this area, having many adventures around here, and a good few black days. This cache is hidden in an area I used to pass by pretty often, and isn't too bad for muggle activity, although it amazes me how much construction is going on in the form of new apartments.
Expect a non-DreamMachine contraption.
