Oh, Mary is a pilot. Time was, glider pilots used to seek out big clouds and do height gain flights in them. Quite a few fell out in rather more pieces than was comfortable and it went out of fashion. Usually now the height gains are done in mountain wave, which has its own points of interest.
I've done some cloud flying in gliders, usually with a turn and slip and a magnetic compass. Speed limiting airbrakes kept it all under control. True luxury is an artificial horizon and a bohli compass, and a GPS.
I always used to pick medium sized cumulus clouds, but sometimes even those could be a bit rough.
I never did find anything worse than Feshiebridge rotor, towing out with the windsocks pointing at each other.......
