"21 Days on a Bicycle" is the story of John and Karen and their bicycle trip in the summer of 2020. Starting and ending in Spokane, Washington State, their sometime humorous, sometimes difficult, adventures take them through parts of Montana, Idaho, and Washington. The book includes John's cross-country drives to and from Spokane. Video and picture YouTube links show some of the spectacular scenery in the USA. A short, hopefully entertaining read.
