Summertime! When clear skies and warm sun lure us to the edge of the river for a float, a swim, a picnic or maybe just a nap on a shady bank. In the old days it was not uncommon to find that the river’s edge had changed from the high waters of winter, with trees and banks shifted, gravel bars moved from one place to the next. But our rivers have been increasingly narrowed by the convenience and stability of roads and other hard surfaces. Still, there are home waters nearby where the river’s shifting compass still holds sway, and somewhere it is getting a chance to meander again.
