The great riding opportunities here in Idaho are still a pretty well hidden secret. We have a lotta roads kinda comparable to that Dragon Tailed thingy that I have read about and seen photos of. The difference is that the Idaho versions are longer, very remote, and if you happen to unfortunately run off the road, you WILL most likely die.
Sensible riding practices are required. There is a Hells Canyon Motorcycle Festival in June with a few thousand participants and a lotta drunken party time. There are many crashes and 1 or 2 deaths every year. Never been,,, and no thanx,,, never will.
The roads end where K & M stopped is where you can catch Jet Boat rides that take you way down into that River Of No Return {if you are in a canoe} and back out. Reservations required and it is an amazing experience. Starting with this section the river then drops, and I do mean drops, into the Columbia River which flows along the Oregon and Washington borders to the Pacific Ocean. Pacific Ocean Salmon spawn up the Columbia, the Snake, the Salmon River, and various tributaries all the way up to Redfish Lake in the Sawtooth Mountains above Lowman where K & M's Idaho ride started. They have to get through 11 or 12 dams, hundreds of Sea Lions, and hundreds of fishing nets and thousands of fisherman.
Amazingly a couple of thousand make it back to that very high up Idaho mountain lake, via a large hatchery close by also. 25 years ago only 1 lone Male made it. They named him Lonesome Larry, took his manly seed, fertilized a few million hatchery produced eggs with it, and sent the babies back down river. It is his studly DNA that help his spawn somehow make it back every year.
If any of you make it thru Idaho on your trips, let me know. If I can swing it, will be happy to ride with you on some interesting 1 day rides within an hour or two of the Boise area that you will not regret.
