Closest is probably skateboard hell in Dearborn...but I think they’re charging now.,..
If your pulling a reefer you might get away with it at Prodce mkt on W Fort
Both bout 5 miles....But in all reality you don’t want to leave a truck unattended ANYWHERE in Detroit metro....
Reality is best bet...Just pay for the couple of nights down at the Detroiter.(Flyin hook)..Fenced and guarded
And catch a cab
Unless you wanna bag the reservation and there’s 2 hotels on other side of 75 from the Detroiter w/reasonable rooms and free truck parking and just get a cab or whatever up to Casino
