Plus I would add that it was sheer luck that an untoned repeater was on a pair that he had programmed. If you're going to the trouble to take a ham HT with you into a remote area, why not take the time to program in the local repeaters?
Yep, and as you probably know, the ARRL produces a pocket-size (3.75 x 5.25 inches) printed repeater directory. I always have one in my vehicle or in my daypack (with my HT). While they publish it every year, Amateurs want to encourage communications, so very little of the existing information changes from one year to the next.
Once a club has a repeater up, it would usually only change the frequency and/or PL/CTCSS tones if they were experiencing/causing interference or there was some other type of problem. Primarily it is additions and deletions.
