In continuing to become familiar with the SOL Author's utilities, I have now discovered how to update one chapter at a time, hence the wayward date in Chapter 13 in Back Trail has been corrected from "1946" to "eighteen forty six," thus disappointing those who thought it might be a secret Time Travel story.
For those so inclined, consider this: we are all time travelers. It's just that our time machines have only a forward setting at 60 mPH. Nor do I require a DeLorean for temporal transiting; my time machine resembles a La-Z-Boy recliner.
