That is nice, nice country you are in ... maybe one of the best kept secrets in good locations to be.
The thing about northern Michigan is that it is a destination. Few pass through it on the way to somewhere else. The peninsula and big waters mean it is never a shortcut. So people who are there MEAN to be there.
Within perhaps ten miles or so of the big lakes and inland chains of lakes there are unlimited wild forage possibilities. Wild food plants abound throughout this area. Seems the growing period is almost zone 6 in many spots, and migrating flocks of birds carry seeds from all over while roosting and foraging on their annual journeys. Autumn olive, of course, is prolific. Many ignored or forgotten pastures and other disturbances can hold many hundreds and thousands of pounds of fruit per
acre. Almost all of it goes untouched by human hands. Really sustains a lot of wildlife ... especially birds. Wild turkeys chow down on them.
imho Autumn Olive makes one of the best fruit wines I've ever tasted. Good
chicken food too.
Other forage? It would take a book ... but one annual treasure breaking out this time of year is the wild leek (aka RAMPS). They cover vast stretches of the upland mixed hardwoods. Can't put a foot down without stepping on leeks ... or morels (I wish).
Also wonderful country for biking and hiking. Got a kayak? Put it on the chain of lakes in Charlevoix and Antrim County and travel otter, heron, loon, wild rice and walleye shorelines for 60 miles...with a thousand places to camp along the way.
Love your country. It seems you've won the Lottery!
