We arrange a truck shuttle with Ann’s parents so they can bike down the Boise river bike path while we go up it. This is an area that is central to the city of Boise and the “green belt”, the lush woods along the banks of the bigger rivers in southern Idaho. I offer to drive the truck back, so Ann gets go both ways and ride with Bob and Carol for a while. The trail ends at the bottom of Lucky Peak dam, the outlet of which floods impressively out of two giant holes that release the Boise river in a double-barreled whitewater torrent to its lower reaches. Emblazoned across the giant dam are the words, “KEEP YOUR FORESTS GREEN”.
