Well, yes and no.. Depends on what you mean by "down the middle of
Michigan" (where's Bill when you need him to define a word, or two)...

If you are passing East of the Detroit B, then it is as I suggested,fly
the Sunrise side of the state down nearly to DET, then down low under
the B, follow the center of the Detroit river (watch for vfr traffic
here), and out across the West end of Lake Erie... This is scenic if
the Wx is nice - downtown Detroit, Belle Isle, Grosse Isle, freighters,
pleasure boats, nuclear power plants, etc. - and you can truck along
just offshore to Ohio...

If you are going West of the Detroit B, then you aim to split the
difference between Ann Arbor and Willow Run airports - there is about a
mile of uncontrolled airspace between the two airport traffic areas
where you don't have to talk to them - easier than Duck soup with a
moving map GPS... Then you angle East, about a 150 deg. heading
initially - so that you stay out of the Detroit B - then just North of
Toledo's airspace you cut across the end of Lake Erie to the Ohio shore
(lots of tall towers in the shore areas so be alert if you are down
low), pass to the South of the Nuclear Plant just before Port Clinton,
and go merrily on your way - watching out for Cleveland, Akron,
etc...... None of this is hard, just be aware of controlled
airspace...

You really need a Detroit Terminal Chart to navigate the Detroit B,
unless ATC is on Valium and handing out clearances through the B to GA
traffic (rare)... This is why I use the Howie Keefe Air Chart
system... That way when I get a wild hair to go somewhere I just pull
out the chart bag and all the charts I need are there...

Yes, there is convective predicted for Thursday for this part of
Michigan... Anyway, if you pass near Saginaw - Browne Airport (KHYX)
Wave at Fat Albert, he'll be snoozing in the hangar.... I'll be slavng
at my office in Hemlock, some 25 miles West of there...

If you have any problems while in Michigan give me a jingle..
