This one has had me stumped all week. I had the merging of rivers at the Missouri Headwaters in my brain, and couldn’t seem to get past it. I didn’t have time to drive down there, so I had to come up with something else. Something at home, preferably. What comes together at home? Well, lots of things, I suppose, but I chose to focus on lunch. What are two things that come together in perfect harmony every day at tables across the globe? Peanut butter and jelly, of course.
