I was out on the streets of San Francisco at lunchtime, when who should appear in the motley crowd of crosswalk pedestrians but two young LDS missionaries, with their signature short-sleeve white shirts, backpacks, nametags, and aura. I didn’t quite stop dead in my tracks, but I did furtively watch them cross Mission on the opposite side of the street and saunter on into the main bus terminal. Granted, there are more than a few folks in that neighborhood who could use the gospel—after they finally make it through detox, get back on their medication, and set things right with their probation officer. It was an odd, unexpected place to find LDS missionaries, but certainly not the only time I’ve had that reaction. What is your most memorable missionary moment?
