Sometimes you see something odd, and it does you good.

I saw that building over the weekend in Long Grove, Illinois, when I visited the town for the first time in many years (sometime after 2004, but not sure when). Long Grove is a prosperous place in southern Lake County — median household income, $148,150 — and a fairly large suburb, about 12 square miles, with a small historic district at the intersection of Old McHenry and Robert Parker Coffin roads.

Long Grove is host to various warm-weather festivals, including chocolate-, strawberry- and apple-themed festivals, but on July 3 this year the historic downtown was quiet, except for a singer entertaining the outdoor patrons at the Village Tavern. The lack of crowds made for pleasant walking, despite the midday heat, especially among the buildings and shops away from the roads.

Businesses clustering around the intersection include (among others) Balanced Earth Energy Healing, Broken Earth Winery, In Motion Dance, Long Grove Apple Haus, Ma and Pa’s Candy, Neumann’s Cigars & More, Olivia’s Boutique, Signature Popcorn, and the Olive Tap, an “olive oil and balsamic vinegar tasting emporium.”

Luxury goods, in other words, largely dependent on the caprices of the upper-middle class. Just walking around I could tell that last year was hard on the district, since a number of businesses looked permanently closed.

Still, most of them seem to have survived, such as Viking Treasures. It promises Scandinavian gifts and was the only place I saw still insisting on a mask.

Long Grove is also known for its small covered bridge.

“The historical significance of the Long Grove Covered Bridge is all about the iron, not the wood,” Aaron Underwood of the Long Grove Historical Society writes. “… our bridge isn’t an ‘authentic’ covered bridge, but rather an iron truss bridge that had a protective covering added in the 1970s to protect that iron and integrate it into the downtown’s historic theme. The cover is a beautiful copy of a famous covered bridge in Ashuelot, New Hampshire.”

Elsewhere, he wrote: “Our bridge is historic because it is rare. Only two bridges of this type remain in the six county Chicago metro area, and only thirty-five remain in the entire state. It may well be the only bridge in the state of this type with such an ornate pedestrian walkway.”

That doesn’t keep morons from driving too-large vehicles into the covering, however.
