Don't you have to show it if you're a soloed

This question came up when I worked at the flight school. The answer
given to our customers by our CFIs was that you must have your student
license and medical with you in the airplane, and if asked in a ramp
check, you must be able to produce a logbook showing the appropriate
solo endorsement, but you don't have to have the logbook with you *in
the airplane* during the flight.
