One of our club pilots found himself low and had to land out. He identified a good field, made a good landing, and on his way to find a phone noticed aircraft flying circuits on an adjacent field
Another pilot in need of a field spotted a windsock and hangar below, set up his approach and became concerned on final that the runway appeared a bit short. He landed just past the fence, got stopped -- and found himself at a model airplane field
Another of our pilots did the same thing in Germany and received a round of applause as he emerged from the glider
There's been a number of gliders that have landed at jail farms or the grounds of mental institutions. Telling head nurse that you have just landed your glider in the back and need to make a phone call initially just gets sympathetic noises and suggestions that it's time for more meds
