#1 - Look west down the Black River from the Military Street bridge. The bank is on your left, Zebra Bar and bowling alley is on your right and you can barely see parts of the 7th Street bridge in the background. In mid-July they have the Port Huron to Mackinac sailboat race with about 200 sailboats and this river is packed. It's like Mardi Gras for a night. They estimate about 100,000 people come to see the boats.
#2 - Looking east across the St. Clair River from the Thomas Edison Inn or the park along the riverfront. You're just south of the Blue Water Bridge and the casino in Sarnia is in the background of the photo. A beautiful place to enjoy the river.
#3 - Unsure, but not in Port Huron because the expressway only has two lanes there. I-94 goes to 3 lanes in the northern Detroit suburbs (23 Mile Road, Chesterfield) so likely somewhere in the Detroit area.
#4 - View of the Blue Water Bridges at night from the Edison Inn. Gorgeous.
#5 - No real clue. Possibly the walkway at Detroit Metropolitan airport or Somerset mall.
#6 - I-94 exit at 8 Mile as you enter (or leave) Detroit.
