The loop as shown in the map below is a 5100+- mile circle of the western USA. I am from Maine, so the first and last parts of my trip will be a fast 4800 miles roundtrip to Yellowstone area.
I've spent the last few weeks pouring over various posts here and on other web sites for good info on roads and sights to see. Great roads are a substantial influence on me...
Boise is a stop over at a friends house, but the rest is a mix that could change. National Parks and Great Roads of the West might be good subtitle.. Starting with the Going to the Sun drive in Glacier National Park, I'll head south to see my Buds in Boise over roads they say are a good ride.. from there west to the coast, with a stop to see Crater Lake.
I am hitting the southern 90 miles of the Oregon coast and the northern 115 miles of the CA coast. If you have ideas here let me know.
I drove Rt 36 in a rental car years ago and am going back for a turn on the bike. It is revered by many on the left coast as one of the best rides going. This route will take me into the valley, which while beautiful, it gets stuffy, so its is east for me through the hills towards reno.
I'm headed for Sequoia and Yosemite, by way of a zig-zag over the Sierra Nevadas between Sacremento and the park. Hwy 36 to Hwy 89 South East to Hwy 49 Southwest to Nevada City, Hwy 20 to I80, Hwy 89 South to 88 southwest to 49 south to 4 back up over to 89 & 395 and then back over the ridge again to the southwest on 108. Once I'm done with that list it is on and through Yosemite & Sequoia. I haven't worked out stop overs yet.
My next destination is the Hoover Dam, but getting there will be interesting. ANY ideas here are welcome. Going through Death Valley seems intimidating from here.
Then on to the North Rim of the Grand Canyon, Zion, Bryce Canyon, Four Corners, Mesa Verde, Million dollar Hwy in CO and a loop of 145 and 550 around Colorado, then north through Aspen over to 191 in Wy Gand Teton & Yellowstone
I plan to "ride like hell" from Maine to Glacier, then relax a bit to make the circle, then book it again from Yellowstone to home.. two 14 hour days up front and two more on the way back should leave time to make the loop 8-10 days. The trip is roughly 10k miles ... 14 hours at an avg speed of 65-75 gets me about 900 miles a day.. Phew.. that is a scary long day. And of course the higher the avg speed the more time I get for the trip.... mind you, if the lovely pillion decides to come, all nets are off and the trip is apt to change drastically...
I've got a nice gps to guide me, and a Valentine one to protect me. I figure I'll be buying tires in Colorado, depending on departure from here... I'm thinking May, late May, or maybe the 1st two weeks of June... September means two plus months past the longest day..
I'm tempted to mount the radar in the 3rd eye...

but then I'll loose rear detection.
Tire repair kit on board.
Just selecting a decent route has been quite an ordeal, but then that is part of the fun.. the planning and packing in ones head.
clues and ideas welcome
Oh yeah, and I may reverse the trip and run it the other way...
