anyone that hasn't thought it worth going gliding should do
I would simply say that anyone who hasn't gone gliding - should!
I actually started on gliders, then moved to power. But gliding is in many ways much more enjoyable, in terms of the experience and satisfaction. Obviously crap at taking wife and kids from A to B, though!
I've also had a balloon flight, and I can heartily recommend the experience.
Not sure I want to pursue it further however, as it is SO much more weather dependent.
