Don't you people have ridges?

I don't think anyone would be likely to get to solo here without being
very aware that the direction the glider is pointing has little to do
with the direction it is moving, and having experienced this a number
of times in 20+ knots winds, at low level, while doing a lot of 180
degree turns, with the instructor pointing it out if the string didn't
stay in the middle.
