ContFmPreviousPhoto => As Robert Pirsig says in ZMM =>
….Twisting hilly roads are long in terms of seconds but are much more enjoyable on a cycle where you bank into turns.:

~7:24 pm Mon 12 Aug: Traveling “The ZMM Route” On Frontage Road Address, 4386 Old US 10, Shown On GSV Strip Map As 1.7 Mile West of Hathaway Eastbound I-94 Rest Area, Rosebud. MT.

The /\ Above /\ Google Street View (GSV) of => Twisting Hilly Road, Is View On Old US-10, Between Forsyth, MT, & Miles City, MT.
….AND … This “Old Hwy 10” is much more enjoyable , and was exactly what I (Henry Gurr) experienced, when I drove Prius through this area in 2019.

Just As => Robert Pirsig’s ZMM Book Passage Says =>”
“….We are just vacationing. Secondary roads are preferred. Paved county roads are the best, state highways are next. Freeways are the worst. We want to make good time, but for us now this is measured with emphasis on “good” rather than “time” and when you make that shift in emphasis the whole approach changes. Twisting hilly roads are long in terms of seconds but are much more enjoyable on a cycle where you bank into turns.
…This ZMM “Emphasis On “Good,” , May Seen Traveling East On “Old Hwy 10” Which, At Many Places Is Not Far From, Or Is Along Frontages To US 12 Combined With I-94.

….HOWEVER: A Conventional Paper Map Will Likely NOT Show These ZMMQuality Roads. Thus You Will Have To Plan Ahead With Your Computer =>
…A) Look these up on an enlarged Internet Map, such as Google Maps OR
…B) MapQuest. OR
…C) Your cell phone may work, except in remote locations. OR
D) As you travel, you learn how to “Spot” a good turn onto a ZMMQuality Road (by intuition) =>
…E) Your discernment may lead to an “ emphasis on “good” rather than “time” ” travel on interesting “ Twisting hilly roads”!! ..****************..

Despite Robert Pirsig’s 1968Trip Statement, He MUST Have Used “The Interstate”, Because Reasonable “Higher Quality” Alternates Were Pretty Much Not Available.
…In the beginning of ZMM Chapter 14, as they ride into Bozeman, MT, The Narrator says ” This interstate freeway we are on must not have existed then.“ [When Phaedrus was teaching 1959-1961]. But by 1968 Narrator’s trip, the Interstate Highway System was generally complete. AND in Montana. Montana Highway Department Maps, Show That by year 1960, The Montana Interstate Highways Are Completed. Click Here. These maps show for example => I-94 runs from North Dakota Border thru Miles City, MT to where it ends with merge with I-90 In Billings, MT. And I-90 continues through Butte, MT to Idaho Border
….From this we conclude this is one of the VERY few places where Mr. Pirsig’s Interstate Highway, memory back his time at MSU, is not correct.

..****************..
…DATE-LINE: Sept 23, 2021. by Henry Gurr.
From ZMM, It Is Not Clear How Much The Narrator Could Travel “Non Interstate”, In Montana, However Much He May Have Wanted To.
….Along the ZMM Route, there many place where Mr Pirsig would have a choice whether or not, to use “The Interstate”. But In many places there is no other reasonable choice. For Examples see A) & C) => .
..A) Traveling West from Miles City, MT would initially have to be I-94. But at Rosebud, MT, going West on Old US 10, would be likely be a very good road choice thru to Hysham, MT.
..B) After Hysham, MT, the alternates to Interstate, are some longer secondary paved roads, which eventually get back to I-90 at Custer, MT Study you map for good choices => 1) Some roads on North Side of Yellowstone River, OR 2) Paved road going SW from Hysham, MT.
..C) Going West from Custer, MT => The Interstate Marginal Roads (Some portions likely Old US 10), are available all the way through Billings, MT, to Laurel, MT.

….Back in 2002, I did my best to find “Non-Interstate”: BUT back at that time, did not realize that I should have started traveling West onto Old US 10 At Rosebud, MT. Thus I failed to photograph many sights likely seen by Narrator, Chris & Sutherlands in 1968.

NEW TOPIC => You Might Try “GSV Driving” (Blue Link Below), Which Will Virtual Reality Travel The Above-Mentioned => “Old Hwy 10” which is much more enjoyable , and was exactly what I (Henry Gurr) experienced, when I drove Prius through this area in 2019.
….INSTRUCTIONS For Google Street View “GSV Driving” Old US 10, 11 Miles East of Forsythe, MT, and ~3 Miles Further East Is Rosebud, MT.
…But this Google Street View Is better, since it => In addition to 360 deg Full Circle Panorama, it offers ability to magnify, and see better the Cattle Guard, the rutted dirt road, + the Line of Trees That Mark The Distant Yellowstone River!!
…Moreover you can, Right Click On The Above Blue Link, and Ask for “Open in a new Tab, Then => Click the Google Street View Image Where you want the “View” To go. Thus you can Click-Click-Click = “GSV Drive” East along the Frontage Road, which is most places is “Old US Hwy 10”. The landscapes along the twists & turns of this old narrow road are FAR more interesting & enjoyable, for a slow and easy car, motorcycle, or even “GSV Drive” !!
…For example, after the above Blue Link comes up, you can turn the GSV toward East, then “GSV Drive” by the grassy road cuts, up onto broad grassy planes, come down where you can see the line of trees by the Yellowstone River, even the river in some places: Then you can “GSV Drive” by A Water Filled Old Yellowstone River Oxbow, see the water level town of Rosebud, THEN go over I-94, get back on Old Hwy 10, and continue down into Tree Lined, Stream, & Curved Road Scene, WHICH IS SHOWN IN /\ ABOVE /\ PHOTO.
