Then again you might meet a fellow PPLer on the apron who turns out to be a gliding instructor and invites you to a trial flight, which shortens the waiting time considerably

. And even though the ratio of groundwork & socializing/actual flying time compared to solo propelled flying is an important barrier from flying gliders for me, too, I readily admit that from a "pure flying feeling" standpoint, gliding is indeed a great way of being airborne.
