Yes, it’s not a nice neighborhood. But you don’t need a gun. Yes, I would stay on the main roads. Take
I-94 Hwy to Conner exit (Detroit City Airport) west to Gratiot, south on Gratiot, ¼ mile to your right (west side) is the cemetery. Those are the main roads. I have lived in the Detroit area and worked all my life. My mother and other relatives are buried there. I go there often through out the year. People (especially if you weren’t raised here) make it out worse then it is. Just stay on the main highways. The safe places to visit in Detroit are, Greek Town, Water front by the Renaissance building, Green Field village, Henry Ford museum, Detroit Historical & Art museum.
