I'm planning a trip to Detroit soon, and will be getting around once I arrive (staying near the airport) by cab. I am considering taking a cab to either Bogart's or Henry VIII, spending time at one of them, walking to the other, and then taking a cab back to the hotel. My doctor has indicated that I should try to be a bit more active during the day, and walking the .8 miles between the clubs seems like a way to do this (which I don't mind). It looks like there is a golf course between them, so it can't be that dangerous to walk there. If it matters, I'd be going in the afternoon and wouldn't be out after dark.
Thoughts?

You can walk. That area of Inkster is an ugly commercial area, but it is not dangerous, especially during the day.
I would not recommend walking between the Detroit strip clubs on 8 Mile Road.
