Nobody could explain why. The whale, quickly nicknamed Humphrey, attracted thousands of onlookers to this small delta town before rescuers -- including an Army Reserve unit piloting landing craft -- managed to guide him back to sea. Then in 2007, it happened again: a mother humpback and her calf, dubbed Delta and Dawn, appeared in the river near town as if the detour were now a family tradition. Rio Vista has always been a place where improbable things show up. Whales. Natural gas fields. Wind farms. Silicon Valley investors buying every acre in sight. The town itself has moved once already -- relocated to higher ground after an 1862 flood drowned the original settlement -- and the habit of adapting to whatever arrives next has become the defining rhythm of life along this stretch of the Sacramento.
