Log book entries

So what's the point? I suppose the entry tallies up another 30 minutes in
the total time column. I'd have another hundred hours in my log book if I'd
tallied up the number of times I sat in the front seat and never touched the
controls. How about riding in the back seat? Or seat 18C on Southwest from
LAX to Phoenix?

You can log what you want as long as it's not fraudulent. Many people
keep their logbooks as sort of a "flying diary" and the remarks are like
"Flew out to Bubbas for Lunch with Bobby and Earl."

I know at least one person who collects famous aviator autographs in
his logbook.

You're right, it counts for nothing.
