It’s called All Things Mysterious, this upcoming special day at the Mity Nice cart and the Sunday Artisan Market. And it will be a day full of surprises and mysteries, with some magic thrown in for good measure.

Yet it started out as a place holder or maybe a joke, when the Mity Nice crew first started planning the Second Sunday events early this spring. We knew we wanted a half year of joyful activities and events, yet we had not yet figured out what our October theme would be. The other five months came to us with ease, but not the last one.

So when we created the schedule and the sweet little postcards that adorn so many refrigerators around town, we wrote in “Mystery” for that month.

Eureka! We had a great idea and eventually we realized it worked perfectly, mixing in a little bit of Halloween with a lot of surprise – including some mystery guests and performers.

So we are sworn to secrecy a lot of this, but some entertainers you’ll recognize from our Mity Nice Street Fair and some are new to the Second Sunday scene. Some may be so mysterious you’ll never know their true identity.

One thing that is no surprise is our Mity Nice Arts & Crafts area, where children and adults play around and make things, whether they be sock puppets, bookmarks or a pirate’s moustache. We’re adding some mystery games near our cart on Detroit Street, too, because games are such fun. (Anyone for another hand of poetry cards?)

What:  A fun family day full of games, crafts, entertainment and many mysteries. (But no mystery meat, we promise. Our cart is all vegetarian and vegan treats!)

When: Sunday, Oct. 14, 11:30 to 3 p.m.

Where: At the Mity Nice cart, on the sidewalk at 303 Detroit Street, and throughout the Sunday Artisan Market

Who: Anyone who enjoys fall, mysteries, sweet treats or art – that’s all of us! Plus our friends from the Leslie Science & Nature Center are coming as our charity partner, and they’re bringing some mystery guests.

Why: Because next to Michigan-made Italian ice and other sweets, what could be more wonderful than a day full of joy and mysteries?

How:  How about creating a secret identity, just for the day of All Things Mysterious. Or maybe you want to pull your copy of Harriet the Spy or Encyclopedia Brown and read something mysterious before you show up.

What else:  We cannot tell you, or it will ruin the mystery and the fun surprises!
