one tuesday a few weeks ago, my parents and I went down to Detroit's Eastern Market. it's basically an open-air farmers market, selling all kinds of produce you would expect to find [and some your wouldn't]. they have food trucks stationed nearby selling artisanal sausages and gourmet mac + cheese. around the market space are a bunch of shops, mostly selling local Detroit and Michigan goods. they also host tailgating for Lions games, and offer yoga classes during off-hours in one of the sheds.
Detroit has had some hard times, but the market has survived. Detroit is a fighter. and a market selling local goods... well that's not just awesome but an economy booster. I highly encourage you to stop by if you find yourself downtown on a tuesday or saturday/sunday. [if only to grab a jar of McClure's spicy bloody mary mix!]
