The shallow water in Northwoods marshes and bays began to crackle with a skim of ice recently, gently reminding everyone that winter is on the way. Ice-up is a firm deadline for many beings who migrate to travel at least a little bit farther south. I got caught up in the flurry of activity and soon found myself in the Mississippi River Flyway swooping around the hills and corners of the Great River Road with other Northerners heading south.
