Original Trip Research

Here are some findings from my research within the book.

General Statistics & Info
States Traveled:
  1. Minnesota
  2. North Dakota
  3. South Dakota
  4. Montana
  5. Wyoming
  6. Idaho
  7. Oregon
  8. California
Gas Stops:
Few gas stops are referenced. I estimate maximum usable range of the Honda at 140 or 150 miles, which may be optimistic. He fills up three consecutive times on Day 14 at shorter intervals. They travel 349 miles that day, the longest of the trip.
  1. Day 2, Ch 5: Hague, ND
  2. Day 3, Ch 6: Lemmon, SD
  3. Day 12, Ch 22: Missoula, MT
  4. Day 13, Ch 25: New Meadows, ID
  5. Day 14, Ch 26: Unity, OR
  6. Day 14, Ch 26: Dayville, OR
    (80 miles from last)
  7. Day 14, Ch 26: Prineville Junction, OR
    (104 miles from last)
Oil Changes:
For some reason the frequent oil changes described in the book attracted my attention. I estimate he performed one every 700 miles or so. He seemed to do them very quickly in parking lots or alleys. Soon I realized he was just dumping the oil on the ground and putting in fresh oil. I guess that's what they did in 1968?
  1. Day 2, Chapt 5
  2. Day 4, Chapt 8
  3. Day 13, Chapt 25
  4. Day 15, Chapt 28
Another trend I noticed throughout the book is the author's preference for chocolate malted milk shakes (referred to only as "malteds" in the book). Yum. Normally ordered at diners with lunch.
  1. Day 2, Chapt 5
  2. Day 13, Chapt 24
  3. Day 14, Chapt 26
  4. Day 14, Chapt 26 (2nd of the day)

Pirsig's Route Summary

As best as I can tell from the information in the book, this is the route and schedule of what occurred.
I believe this site to be the most accurate representation of the actual trip that can be found on the web.

Information here was put together largely from close study of the location references in the book, followed by some logic and deduction, and lastly some gaps are filled in by research done by other people that can be found on the web. I use that as a last resort because in most of those cases there is no data to back up their assertions, and I've found a few of them to be incorrect.
