For me, looking to get back in the air after a long layoff, the only logbook I can locate is my little blue one with my first 100 jumps. Somewhere in all the moves over the years my Precision Freefall log has been lost and I'm bummed. At first I was bummed that I have no record of a big chunk of my jumping but what disappoints me more is not having record of all the cool, interesting people I met along the way.
