Logging local flights.

I am curious about how people choose to log local flights where you
might fly over another airport or city, but not land there.

For example, on a nice day I might make an hour or hour and a half
"grand tour" over several nearby cities, just for the pleasure of
looking at the changing countryside, and then land back at my home airport.

No FAR issues, of course, but wonder if most people just enter it as
"KXYZ LCL", or cite the cities or airports flown over but not landed at.

Second, what is your preference if you make a flight involving several
intermediate stops, all in one day? If it's a major cross country, I'll
log each leg on a separate line, but if it's just "A" to "B" to "C" to
"A"... do you log each leg separately or show it as multiple entries on
a single line with the grand total time for the trip?

Third, I've been using a simple Excel spreadsheet to summarize the time
which is offically kept in a standard logbook. A formal computerized
logbook seems like "overkill" to me, but I'd be interested in comments
from people who have a favorite computerized logbook, and what features
they particularly like.
