I'm going to check out a vehicle on the east side of Detroit on Friday. I know from going to Harpo's years ago this is a really bad area of town. Was hoping the seller would be able to meet me at a public place but said vehicle isn't in good running condition so I have to meet at his house. Bringing my cousin who has a background in law enforcement but doesn't have a CPL. Said he might bring a shotgun and keep it in the truck, lol. Any tips before I travel to the Devil's Lair?
