Larkins Draw Bench Distance Trial
Seven public benches installed at measured intervals from the shoulder form the County Bench Distance Trial at the south edge of Larkins Draw, beside a farm-to-market road and a county drainage pond, each with a small sign describing sightline, dust, and conversational effects. It is apparently maintained by the Menard-Larkins County Roadside Amenities Subcommittee, whose stencil appears on the trash receptacle. The benches were reportedly arranged as a permanent demonstration after a disagreement over how close roadside seating ought to be to traffic during a 1990s rest-stop improvement program. The fourth bench, set neither near nor far enough to satisfy anybody, appears to be the one most often photographed.

The Drive-Thru Tabernacle
Services are posted for 9:00 and 10:45, and the drive-thru lane along the east wall of Dosher First Tabernacle opens twenty minutes before each — a schedule unchanged since the lane was added in 1978 to resolve what the cornerstone of the addition calls, in full, "the seating question." The lane wraps the sanctuary under a shallow metal canopy, passes a menu-board-style hymn display, and exits past a speaker post from which communion was administered by intercom between 1978 and 1994. The intercom practice ended by unanimous vote of the elders, recorded in minutes that state the motion, the count, and nothing else. The lane remains striped, the arrows were repainted as recently as last spring, and the speaker post stands under a fitted canvas cover, which suggests continued maintenance of something formally discontinued. Whom to ask about the vote is not obvious; the elders named on the sign are, by now, presumably emeritus.
