Dear Readers, I’m writing this from the SweetSpot, where people come for coffee, muffins, and conversation. Many regulars are lifelong residents of the city pop. 15,000. Others are students at the University of Wisconsin campus here, just up the road. Lacey Reichwald, the cafe’s owner, bought the place a while back to give those very different neighbors — who often misunderstand one another — a place to gather under the same roof.
