several years ago some one offered a flight log here in Pa . it was a useful item but had some things i felt unneeded, cluttered & not enough room for comments. I used it a lot for training esp. two or more people. i could copy it & give to student as well as refer to and see where we left off last time.very good to refer back to and see weather , comments on trim, problems encountered etc.if you travel it would be a great place to contain field maps, phone # etc the idea isa good one but just has not seen wide spread use.
