"Prepare to Fly - Paragliding Tips I Wish I'd Learned Sooner" is an extensive collection of advice aimed at the novice and progressing paraglider pilot, which includes many personal lessons gleaned from Simon Blake's own logbook and experience of going from newly-minted Club Pilot to keen cross-country flyer. One of the key pieces of advice early in that book is to keep a log of your flights.
This is NOT that book. This is YOUR logbook. Fill it in every time you fly... and learn.
