A friend of mine joined my gliding club with a PPL. He still flies power but now he has a part-share of a syndicated glider he will get the tug out if it's not his day. He had to do tailwheel conversion and so on, and had his Silver.
Had an interesting tow when learning it, only one magneto was on apparently as the instructor & I got a very close look at the trees at the end of the airfield. Also had what could have been nasty the first tow in my own glider - not quite enough forward trim, it shot up on taking to the air and I pio'd along behind the tug for what felt like forever.
